    Appellant.
    On review from the Iowa Court of Appeals.
    Appeal from the Iowa District Court for Polk County, Arthur E.
    Gamble, Judge.
    The State seeks further review of a decision of the court of appeals
    reversing   the    defendant’s   second-degree   murder   conviction   for
    insufficient evidence. DECISION OF COURT OF APPEALS VACATED;
    DISTRICT COURT JUDGMENT AFFIRMED IN PART AND REVERSED
    IN PART AND CASE REMANDED.

    Attorney, and Daniel Voogt and Stephanie Cox, Assistant County
    Attorneys, for appellee.

    MANSFIELD, Justice.
    This case requires us to consider whether substantial evidence
    supports the second-degree murder conviction of an individual who
    struck the first, nonlethal blow in a fatal beating. The defendant’s blow
    knocked the victim down. Others in the group surrounding the victim
    then kicked and stomped him to death.
    We conclude that substantial evidence supports the jury’s guilty
    verdict on theories of both principal liability and accomplice liability.
    However, there is not substantial evidence to support the theory of joint
    criminal conduct that was also submitted to the jury.       Since the jury
    returned a general verdict of guilty, and the possibility exists that one or
    more jurors found the defendant guilty only on the basis of the invalid
    theory of joint criminal conduct, we must reverse the defendant’s
    conviction and remand for a new trial. In doing so, we affirm the district
    court’s evidentiary ruling relating to prior fighting by the defendant and
    others who assaulted the victim.
    I. Facts and Procedural Background.
    We recite the facts in the light most favorable to the State. State v.
    Neiderbach, 
    837 N.W.2d 180
    , 187 (Iowa 2013). On the night of August
    24–25, 2013, a crowd of twenty to forty teenagers was gathered at an
    empty lot next to the Des Moines River in downtown Des Moines. They
    were drinking, dancing, and listening to music. About ten to fifteen cars
    were present. Some in the crowd were dancing on the cars.
    Richard Daughenbaugh, a forty-year-old man who was under the
    influence of alcohol and methamphetamine, pulled up in his truck
    uninvited. He honked his horn repeatedly at one of the male teenagers
    present, insisting he move out of the way so Daughenbaugh could park.
    After they had exchanged words, Daughenbaugh parked his vehicle.
    3
    Daughenbaugh then got out of his vehicle and began mingling, dancing,
    and drinking with the crowd for about fifteen minutes.
    Isiah Berry had been fishing with his girlfriend Monica Perkins
    nearby for most of the day. He gave up trying to fish because one of the
    teenagers had grabbed his fishing pole and made a sarcastic comment
    when Berry asked for it back. Berry and Perkins were making plans to
    go home. But they stayed when Perkins saw a situation that made her
    believe something was about to happen.
    A group of the partiers had surrounded Daughenbaugh. One of
    the people in the group, the defendant Kent Tyler, threw a punch at
    Daughenbaugh’s face that knocked him to the ground. 1 Daughenbaugh
    moved on the ground and tried to get up. He never did get up. Members
    of the group immediately jumped and stomped on Daughenbaugh as he
    was   lying    on   the   ground.       While    he   was    being    stomped      on,
    Daughenbaugh was helpless, doing nothing to defend himself.
    Perkins rushed over and threw herself on top of Daughenbaugh,
    attempting to protect him. When one person tried to kick Perkins, Berry
    ran in to rescue his girlfriend. An assailant hit Berry from behind; Berry
    hit his assailant back.       Eventually some of the partiers chased Berry,
    tripped him, hit him, and stomped on him as well.
    1Witnesses   offered differing accounts as to whether Daughenbaugh did anything
    to provoke Tyler’s punch. Perkins and B.B. (a seventeen-year-old who was part of the
    gathering) testified that Daughenbaugh was just partying and not causing any trouble.
    Some members of the gathering testified that Daughenbaugh walked up to Tyler, or that
    Daughenbaugh touched or pushed up against Tyler.
    Likewise, witnesses differed as to what Tyler did after punching Daughenbaugh.
    One witness from the group of partiers (L.S.) testified Tyler walked away. Another
    witness (E.R.) testified Tyler hit Daughenbaugh but did nothing else thereafter. On the
    other hand, Perkins testified, “I think it was the one guy [who] hit his face [who]
    stomped on his face.”
    4
    Perkins made a frantic call to 911 and tried to describe what was
    happening. Two girls in the crowd grabbed Perkins’s phone from her and
    threw it away. Still, the call went through long enough that police soon
    arrived.
    Berry suffered bruises and abrasions. Daughenbaugh died from
    his injuries.   Although Daughenbaugh also had facial abrasions and
    bruising, the autopsy revealed that the cause of his death was a severely
    torn mesentery, leading to internal bleeding.      The mesentery is the
    membrane connecting several body organs to the posterior abdominal
    wall. Daughenbaugh’s mesentery was torn due to his being kicked and
    stomped on when he was unable to defend himself.          As the medical
    examiner later explained, a torn mesentery is typically seen in child
    abuse cases but is unusual in the case of an adult like Daughenbaugh
    who can normally protect himself. The medical examiner added, “[T]hese
    injuries from a forensic standpoint indicate that the victim, the decedent,
    was probably unable to defend himself at the time the blows were
    rendered to the abdomen.”
    The next day, Tyler was Mirandized and interviewed. He admitted
    he had attended the party by the river that night. However, he claimed
    he had been sitting in a parked car playing music at the time and had no
    involvement in the beating whatsoever.
    Tyler and three others—James Shorter, Yarvon Russell, and
    Leprese Williams—were subsequently charged with first-degree murder.
    See Iowa Code § 707.2 (2013). The cases were severed for trial. Tyler’s
    case went to trial from December 9 through December 17. In addition to
    first-degree murder, the jury was instructed on the lesser included
    offenses   of   second-degree   murder,   attempted   murder,    voluntary
    manslaughter, willful injury causing serious injury, willful injury causing
    5
    bodily injury, involuntary manslaughter by public offense, involuntary
    manslaughter by act, assault with intent to inflict serious injury, assault
    causing serious injury, assault causing bodily injury, and assault.
    At trial, the State’s witnesses included B.B. 2 She testified that she
    saw a group form around Daughenbaugh that included Tyler, Shorter,
    Russell, and Williams. Over Tyler’s objection, she also testified that she
    wanted to leave at that point because she had seen them fighting before,
    she knew what was going to happen, and she didn’t want to be a part of
    it. She testified that although she did not see who struck the first blow,
    she did see Daughenbaugh fall to the ground and get beaten.
    On first-degree murder, the jury was instructed that they could
    find Tyler guilty as a principal or under an aiding and abetting or joint
    criminal conduct theory. Thus, the instruction read as follows:
    The State must prove all of the following elements of Murder
    in the First Degree:
    1. On or about August 25, 2013, the defendant, individually or
    through joint criminal conduct or through aiding and
    abetting another and without justification, assaulted Richard
    Daughenbaugh.
    2. Richard Daughenbaugh died as a result of the assault.
    3. The defendant, individually or through joint criminal
    conduct or someone he aided and abetted, acted with malice
    aforethought.
    4. The defendant, individually or through joint criminal
    conduct or someone he aided and abetted, acted willfully,
    deliberately, premeditatedly and with a specific intent to kill
    Richard Daughenbaugh.
    The court’s second-degree murder instruction restated these same
    elements, except it omitted the fourth element of a specific intent to kill.
    2We   refer to the juvenile witnesses by initials only.
    6
    The jury acquitted Tyler of first-degree murder, but found him
    guilty of second-degree murder. See 
    id. § 707.3.
    It did not reach the
    remaining lesser included offenses. The court overruled Tyler’s motions
    for judgment of acquittal and for new trial and sentenced Tyler to fifty
    years imprisonment. See 
    id. § 707.3;
    id. § 902.12(1).
    
    Tyler appealed, arguing there was insufficient evidence to support
    his conviction on any of the three murder theories. In addition, Tyler
    asserted the district court erred in admitting B.B.’s testimony that when
    the group formed around Daughenbaugh including Tyler, Shorter,
    Russell, and Williams, B.B. wanted to leave because after having seen
    them fight in the past, she thought fighting was going to happen again.
    We transferred Tyler’s appeal to the court of appeals. That court
    reversed Tyler’s second-degree murder conviction, finding insufficient
    evidence to support any of the three theories advanced by the State at
    trial—i.e., principal liability, aiding and abetting, or joint criminal
    conduct. 3    One member of the panel dissented and would have found
    sufficient evidence to support the aiding and abetting and joint criminal
    conduct theories. We granted the State’s application for further review.
    II. Standard of Review.
    As we explained recently,
    We review sufficiency-of-evidence claims for correction
    of errors at law. In reviewing the evidence, we view the
    evidence in the light most favorable to the State. “[W]e will
    uphold a verdict if substantial evidence supports it.”
    “Evidence is considered substantial if, when viewed in the
    3It is not clear why the court of appeals remanded for entry of a judgment of
    acquittal instead of just vacating the second-degree murder conviction and remanding
    for further proceedings. There was clearly sufficient evidence to support a conviction on
    some of the lesser included offenses as to which the jury had been instructed but did
    not reach, even if the evidence were deemed insufficient to sustain a second-degree
    murder conviction.
    7
    light most favorable to the State, it can convince a rational
    jury that the defendant is guilty beyond a reasonable doubt.”
    State v. Rooney, 
    862 N.W.2d 367
    , 371 (Iowa 2015) (citations omitted)
    (quoting State v. Sandford, 
    814 N.W.2d 611
    , 615 (Iowa 2012)).                 “We
    review evidentiary rulings regarding the admission of prior bad acts for
    abuse of discretion.” State v. Putman, 
    848 N.W.2d 1
    , 7 (Iowa 2014).
    III. Sufficiency of the Evidence.
    For reasons that will be discussed below, we must address all
    three theories of criminal liability that were presented to the jury. We
    should be clear at the outset what Tyler does and does not challenge. He
    does not dispute there was substantial evidence that he threw the first
    punch that knocked Daughenbaugh to the ground.
    A.     Liability as a Principal.         On the individual liability theory,
    Tyler challenges only the State’s evidence of causation.               He does not
    dispute the State presented substantial evidence on the other elements,
    including malice aforethought.
    To find Tyler guilty on a theory of individual liability, the jury had
    to conclude that Tyler’s own personal assault on Daughenbaugh caused
    Daughenbaugh’s death. 4          While there is certainly evidence that Tyler
    started a chain of events by punching Daughenbaugh in the face and
    knocking him to the ground, the autopsy indicated that none of the
    blows to Daughenbaugh’s head were fatal. Rather, Daughenbaugh died
    as a result of tears in his mesentery that occurred when members of the
    group stomped and kicked on his abdomen when he was down. Tyler
    relies on these facts to urge that an individual liability theory of guilt
    should not have been submitted to the jury.
    4The   jury was not given a separate instruction on causation.
    8
    The State responds in two ways. First, on this record, it argues the
    jury was entitled to find that Tyler participated in the kicking and
    stomping.       Second, it argues that without Tyler’s initial punch,
    Daughenbaugh would have not have been rendered helpless and then
    killed by the subsequent kicking and stomping. In other words, Tyler’s
    initial punch was a but-for cause of Daughenbaugh’s death.
    The first of these arguments does not convince us.                 No witness
    testified that Tyler (or someone identified through other testimony as
    Tyler) was one of the persons kicking or stomping on Daughenbaugh’s
    abdomen. True, substantial evidence exists that Tyler remained in the
    group circling Daughenbaugh after Daughenbaugh fell. 5                 But everyone
    agreed there were a number of individuals in that group, and to draw the
    inference that Tyler delivered one of the fatal blows requires guesswork
    and speculation.
    However, we find the State’s alternative argument more persuasive.
    In our recent decisions addressing questions of causation in criminal
    law, we have applied the Restatement (Third) of Torts. Thus, in State v.
    Tribble, 
    790 N.W.2d 121
    , 126–27 (Iowa 2010), we cited the Restatement
    (Third) of Torts: Liability for Physical and Emotional Harm §§ 26–27, at
    346, 376 (Am. Law. Inst. 2010) [hereinafter Restatement (Third)] as well
    as our opinion in Thompson v. Kaczinski, 
    774 N.W.2d 829
    , 836–39 (Iowa
    2009). We said,
    When causation does surface as an issue in a criminal case,
    our law normally requires us to consider if the criminal act
    was a factual cause of the harm.
    5One   of the teenagers, L.S., testified that she saw “the kid hit [Daughenbaugh]
    and then walk off.” But she was the only witness to so testify and Perkins testified to
    the contrary.
    9
    The conduct of a defendant is “a factual cause of harm
    when the harm would not have occurred absent the
    conduct.” We have traditionally labeled this straightforward,
    factual cause requirement of causation the “but for” test. It
    operates to identify factual causation in each instance, but
    requires further assistance when multiple acts occur, each of
    which alone would have been a factual cause in the absence
    of the other act or acts. This assistance now comes in the
    form of a legal principle to govern the outcome. When such
    multiple causes are present, our law declares each act to be
    a factual cause of the harm.
    
    Tribble, 790 N.W.2d at 126
    –27 (citations and footnote omitted) (quoting
    Restatement (Third) § 26, at 346).
    In State v. Hennings, we expressly relied on Tribble’s “but for” test
    in upholding the defendant’s hate-crime conviction for driving his pickup
    truck at a group of African-American boys walking in the street after
    getting in an argument with them. 
    791 N.W.2d 828
    , 835–36, 839 (Iowa
    2010). We explained,
    To find a causal connection, the jury need not believe the
    only motivation for the defendant’s acts was the victim’s race
    or other protected status. Instead, to find a defendant guilty
    under [Iowa Code] section 729A.2, the jury must determine
    beyond a reasonable doubt the defendant would not have
    acted absent the defendant’s prejudice.
    
    Id. at 835.
      We concluded, “[T]here is substantial evidence Hennings
    would not have run the boys down with his truck, and run over A.M.,
    except for the boys’ race.” 
    Id. Then, in
    State v. Adams, we dealt with a case where an allegedly
    intoxicated motorist ran into and fatally killed a bicyclist who was riding
    in the same direction as the motorist on a heavily traveled street late at
    night when the right headlight on the motorist’s car was not functioning.
    
    810 N.W.2d 365
    , 367, 373 n.9 (Iowa 2012). The motorist was convicted
    of unintentionally causing the death of another by operating a motor
    vehicle while intoxicated, a Class B felony. 
    Id. at 367–68;
    see Iowa Code
    10
    § 707.6A.   We indicated that Tribble had “clarified” the principles of
    causation to be applied in a criminal case and said, “Except where
    multiple acts contribute to cause a consequence, the determination of
    factual causation turns simply on whether ‘the harm would not have
    occurred absent the [defendant’s] conduct.’ ” 
    Adams, 810 N.W.2d at 372
    (quoting 
    Tribble, 790 N.W.2d at 127
    ). We characterized Adams’s case as
    a “normal” one and stated that “the causation question in a prosecution
    under Iowa Code section 707.6A(1) asks whether the victim’s death
    would have occurred in the absence of the defendant’s criminal act—
    intoxicated driving.”   
    Id. We then
    reserved for possible postconviction
    proceedings the question whether Adams’s counsel had been ineffective
    in failing to raise as a defense the lack of a causal connection between
    Adams’s alleged intoxicated driving and the victim’s death. 
    Id. at 372–
    74.
    There is substantial evidence that Tyler’s punch was a but-for
    cause of Daughenbaugh’s death. This blow knocked Daughenbaugh to
    the ground and he never got up. A reasonable jury could infer that if
    Tyler had not hit Daughenbaugh, knocked him to the ground, and put
    him in a position of relative helplessness, he would not have died that
    night from the stomping and kicking that immediately followed.
    Tyler counters that “[c]ausation in the criminal context is not
    satisfied by simply showing some attenuated set of circumstances by
    which one could argue there is ‘but for’ causation,” and cites to State v.
    Garcia, 
    616 N.W.2d 594
    , 596–97 (Iowa 2000). The Garcia decision does
    not support Tyler, however.       For one thing, Garcia states that “[t]he
    principles of causation normally associated with civil tort litigation are
    pertinent in criminal cases.”     
    Id. at 596.
      Those tort principles have
    evolved in recent years.      In 2009, for tort purposes, we adopted the
    11
    Restatement (Third) on causation. See 
    Thompson, 774 N.W.2d at 839
    .
    Then, in a succession of criminal cases in 2010 and 2011, we applied
    our updated law of tort causation from Thompson and the Restatement
    (Third) in the criminal context.           See 
    Adams, 810 N.W.2d at 372
    ;
    
    Hennings, 791 N.W.2d at 835
    ; 
    Tribble, 790 N.W.2d at 126
    –27. In Adams,
    we quoted from State v. Dalton, 
    674 N.W.2d 111
    , 118 (Iowa 2004), which
    takes a similar view of causation to Garcia, only to distance ourselves
    from that quotation by explaining how we had clarified the law of
    criminal causation in Tribble. See 
    Adams, 810 N.W.2d at 372
    . Tyler fails
    to mention, let alone address, our recent criminal caselaw on causation.
    Moreover, Tyler’s parade of horribles is overstated.      Tyler argues
    that if the State’s view of causation were correct, other individuals and
    entities could be criminally liable for Daughenbaugh’s death on a but-for
    basis.      In Tyler’s view, this includes the drug dealer for selling
    methamphetamine to Daughenbaugh, the City of Des Moines for creating
    a desirable party locale by the Des Moines River, and Daughenbaugh’s
    family     for   failing   to   prevent    him   from   drinking   and   using
    methamphetamine that night.               This line of argument, however,
    disregards the other elements that would need to be established as a
    prerequisite to criminal liability, including malice aforethought in the
    case of murder.
    Additionally, the chain of causation here is far from attenuated. A
    group surrounded Daughenbaugh in what outsiders viewed as a
    threatening situation; one person in the group, the defendant, struck
    Daughenbaugh and knocked him to the ground; others in the group
    promptly kicked and stomped him in the abdomen until he died. Even if
    “proximate cause” or what we now call “scope of liability” remains part of
    the State’s causation burden in a criminal case, see Thompson, 
    774 12 N.W.2d at 837
    , that burden was met here. Substantial evidence exists
    that a group assault on a mismatched and intoxicated Daughenbaugh
    was a reasonably foreseeable consequence or within the range of harms
    of Tyler’s initial act of knocking down Daughenbaugh with a punch to his
    head. See 
    id. at 838–39.
    Thus, under pre-Tribble caselaw, we believe a reasonable juror
    could find not only that Tyler’s blow was a but-for cause of
    Daughenbaugh’s death, but also that it “create[d] the kind of dangerous
    condition that would make [the ensuing lethal blows] more likely to
    occur.” 
    Garcia, 616 N.W.2d at 597
    (alteration added) (quoting State v.
    Murray, 
    512 N.W.2d 547
    , 550 (Iowa 1994)).        To put it another way, a
    reasonable juror could find that the fatal kicking and stomping was “part
    of a chain of events set in motion by the assailant’s act and leading
    directly to the victim’s death.” 
    Murray, 512 N.W.2d at 550
    . “It is not
    essential for conviction in all cases that the accused actively participated
    in the immediate physical impetus of death.” State v. Marti, 
    290 N.W.2d 570
    , 579 (Iowa 1980).
    Again, accepting the State’s version of the facts, after a group
    surrounded Daughenbaugh, Tyler threw the first punch without
    provocation, knocking Daughenbaugh to the ground. Others then joined
    in, kicking and stomping on Daughenbaugh once he was down—thereby
    killing him. To put it another way, if Daughenbaugh’s estate sued Tyler
    for wrongful death, would the estate be able to get to the jury on the
    question of causation under either current or former Iowa tort
    principles? We think the answer is clearly yes. See State v. Hubka, 
    480 N.W.2d 867
    , 869 (Iowa 1992) (“It is well-established that the definition of
    ‘proximate cause’ in criminal cases is identical to its definition in civil
    cases.”); State v. McFadden, 
    320 N.W.2d 608
    , 613, 616–17 (Iowa 1982)
    13
    (finding that “ordinary proximate cause principles” applied to causation
    in an involuntary manslaughter case and that “the record contains
    substantial evidence that defendant’s participation in a drag race with
    [the driver of another vehicle] was a concurring proximate cause of the
    accident in which [the driver of the other vehicle and the driver of a third
    vehicle] were killed”).
    Notwithstanding their use of the Restatement (Third) to analyze
    criminal causation, Tribble and Adams left open the possibility that
    criminal causation might still require more than proof of but-for factual
    causation.     Thus, in Tribble we observed that “[t]he nature of the
    argument presented by Tribble in this case does not require us to
    consider the element of causation beyond a factual-cause 
    analysis.” 790 N.W.2d at 127
    n.1. In Adams we likewise said that we “do not address
    today whether the ‘legal cause’ aspect of the former proximate cause
    doctrine has any continuing viability in criminal cases after our decision
    in Thompson v. 
    Kaczinski.” 810 N.W.2d at 372
    n.7. For reasons we have
    already discussed, we need not resolve that question today either. Even
    if criminal causation—unlike tort causation—still embraces notions of
    proximate or legal cause, we would find that substantial evidence
    supports a finding of proximate causation in this case.
    B.     Liability as an Aider and Abettor.    We now turn to Tyler’s
    potential criminal liability as an aider and abettor. We have said,
    To sustain a conviction on the theory of aiding and abetting,
    the record must contain substantial evidence the accused
    assented to or lent countenance and approval to the criminal
    act either by active participation or by some manner
    encouraging it prior to or at the time of its commission.
    14
    State v. Spates, 
    779 N.W.2d 770
    , 780 (Iowa 2010) (quoting State v.
    Tangie, 
    616 N.W.2d 564
    , 574 (Iowa 2000)). 6
    Tyler     contends      there     is   insufficient    evidence    he   actively
    participated in the beating or in some manner encouraged it prior to or
    at its time of commission.            We disagree.     While Tyler takes it as an
    undisputed fact that he walked away after hitting Daughenbaugh, this
    was the testimony of only one witness, L.S. No one else testified that
    Tyler left the crowd that had formed around Daughenbaugh.                        And
    Perkins testified,
    They started with the one. I think it was the one guy hit his
    face stomped on his face. They didn’t just stomp on his face.
    They jumped up in the air and stomped on his face like he
    was a trampoline.
    The jury was entitled to find the testimony of Perkins, a Good Samaritan
    who tried to rescue Daughenbaugh, more credible than that of L.S., a
    sixteen-year-old who stood by and may have been friends with some of
    the perpetrators.
    Furthermore, Tyler’s act of decking Daughenbaugh with a punch
    to his face after a crowd had surrounded Daughenbaugh could be
    regarded as encouragement for what subsequently happened—i.e.,
    further   beating       of   Daughenbaugh          once     he    hit   the   ground.
    Circumstances matter. Viewing the evidence in the light most favorable
    to the State, this is not a case where Tyler simply hit someone at random
    and would have been astonished to see others continue the beating.
    Rather, a crowd including Tyler encircled Daughenbaugh—an older,
    intoxicated person who had barged rudely and uninvited into a large
    teenager party. At that point, Tyler threw the first punch that knocked
    6The   jury was given an instruction consistent with this law.
    15
    Daughenbaugh down.              The State’s aiding and abetting theory is that
    Tyler’s punch was at least as much encouragement as a “let’s get him”
    statement would have been.
    Perkins   testified    that   when   she    saw    the   crowd     around
    Daughenbaugh, she told her boyfriend Berry they shouldn’t leave
    because “something is about to happen.” B.B. testified that when she
    saw the crowd form around Daughenbaugh, she wanted to leave because
    “I know what’s going to happen, and I don’t want to be a part of it.” A
    reasonable jury could find that when Tyler struck Daughenbaugh, he
    expected and intended that others would continue the beating. 7 We find
    sufficient evidence to support a jury verdict that Tyler aided and abetted
    in the murder of Daughenbaugh. See, e.g., 
    Spates, 779 N.W.2d at 777
    –
    78 (finding that a participant in a gun battle between two rival groups
    could be liable for aiding and abetting the shooting death of a bystander
    even if the fatal shot was fired by a member of the other group); Fryer v.
    State, 
    325 N.W.2d 400
    , 406 (Iowa 1982) (noting that aiding and abetting
    “may be inferred from circumstantial evidence including presence,
    companionship and conduct before and after the offense is committed”).
    In rejecting the aiding and abetting theory in this case, the court of
    appeals conceded a jury could find that Tyler knew others would assault
    Daughenbaugh, but questioned the evidence that Tyler intended a
    deadly assault to occur. At oral argument before us, Tyler picked up on
    this theme, challenging the evidence that he intended Daughenbaugh be
    killed.     This line of argument, however, conflates malice aforethought,
    which is required for second-degree murder, with a specific intent to kill,
    7The
    three persons identified at trial as kicking and stomping on Daughenbaugh
    included Williams, who was Tyler’s half-brother. Williams arrived at the party with
    Tyler and also left with him.
    16
    which is only an element of first-degree murder. Tyler was acquitted of
    first-degree murder.
    We     recently     elaborated     on     the   distinction     between      malice
    aforethought and specific intent to kill in State v. Ceretti, 
    871 N.W.2d 88
    ,
    93–94 (Iowa 2015), emphasizing that the former concept is broader than
    the latter.     “Malice aforethought requires the actor to have ‘a fixed
    purpose or design to do physical harm to another that exists before the
    act is committed.’ ” State v. Lyman, 
    776 N.W.2d 865
    , 877 (Iowa 2010)
    (quoting State v. Myers, 
    653 N.W.2d 574
    , 579 (Iowa 2002)).                       Thus, in
    Myers, we found a factual basis to support a second-degree murder
    guilty plea in a fatal shaken baby case based on the defendant’s
    admissions that she knew “some” physical harm and “some” injury
    would occur to the 
    baby. 653 N.W.2d at 579
    –80; see also State v.
    Baratta, 
    242 Iowa 1308
    , 1314, 
    49 N.W.2d 866
    , 870 (Iowa 1951) (“It is
    evident that an assault need not be made with a deadly weapon before
    malice can be inferred.”).         There was sufficient evidence from which a
    jury could infer that Tyler intended others to assault Daughenbaugh and
    thus, that Tyler had the required mental state of malice aforethought. 8
    C.     Joint Criminal Conduct.              Lastly, we consider the State’s
    theory of joint criminal conduct.            Joint criminal conduct is defined as
    follows:
    When two or more persons, acting in concert,
    knowingly participate in a public offense, each is responsible
    for the acts of the other done in furtherance of the
    commission of the offense or escape therefrom, and each
    8Furthermore,     the district court’s instruction, to which Tyler did not object,
    defined “malice aforethought” consistent with the foregoing caselaw: “ ‘Malice
    aforethought’ is a fixed purpose or design to do some physical harm to another which
    exists before the act is committed.” It is settled law that the instructions, if not objected
    to, become the law of the case. See State v. Merrett, 
    842 N.W.2d 266
    , 275 (Iowa 2014).
    17
    person’s guilt will be the same as that of the person so
    acting, unless the act was one which the person could not
    reasonably expect to be done in the furtherance of the
    commission of the offense.
    Iowa Code § 703.2.
    Joint criminal conduct “contemplates two acts—the crime the joint
    actor has knowingly participated in, and a second or resulting crime that
    is unplanned but could reasonably be expected to occur in furtherance of
    the first one.” State v. Rodriguez, 
    804 N.W.2d 844
    , 852 (Iowa 2011). In
    Rodriguez, we found that a guilty plea to vehicular homicide was
    factually supported on a joint criminal conduct theory. 
    Id. at 853.
    In
    that case, the defendant was not the driver; however, the defendant was
    a passenger who had participated in a gas theft by actually pumping the
    unpaid-for gas. 
    Id. at 846.
    The homicide then occurred when the driver
    left the gas station at a reckless rate of speed. 
    Id. We concluded
    that the
    defendant had jointly participated in the first crime—i.e., the gas theft—
    and the vehicular homicide was a reasonably foreseeable consequence of
    the quick escape from the scene of the crime that was in furtherance of
    the original crime. 
    Id. at 853.
    The court of appeals found that even when the facts are viewed in
    the light most favorable to the State, Tyler could not have reasonably
    foreseen that a subsequent beating would occur in furtherance of his
    initial blow to Daughenbaugh. For reasons we have already discussed,
    we respectfully disagree.         However, we think there is a different
    evidentiary hole in the State’s joint criminal conduct theory.      As we
    discussed in State v. Smith, 
    739 N.W.2d 289
    , 293 (Iowa 2007), our older
    caselaw on joint criminal conduct “blurred the line between the
    commission of a crime by means of aiding and abetting and joint
    18
    criminal conduct.” 9 It is now clear that there must be a joint crime in
    which the defendant participates, followed by a second crime that may
    have been unplanned but involved reasonably foreseeable conduct in
    furtherance of the first crime. Rodriguez is a good example of this.
    Here the evidence could allow a reasonable jury to find two
    crimes—i.e., two separate assaults. But the problem is that the jury also
    had to have found Tyler acted in concert when he committed the first
    crime, namely, his assault on Daughenbaugh. Although the question is
    close, we think this requires too much speculation given this record. A
    jury would have to find there was a plan in place among Tyler and
    others, such as Williams, Russell, and Shorter, to fight Daughenbaugh at
    the time Tyler struck the first blow.           While the fact that a crowd
    surrounded Daughenbaugh might be some evidence of such a plan, it is
    not substantial evidence.
    The State analogizes the present case to State v. Hohle, 
    510 N.W.2d 847
    (Iowa 1994), but that is one of those older cases whose vitality has
    been called into question by Smith. In Hohle, the defendant committed
    an assault individually against Lumbard and then was involved in a
    follow-up joint assault against Lumbard and Gourdie in which Gourdie
    was injured.    
    Id. at 848.
       The State prosecuted both assaults and the
    defendant was convicted of both.          
    Id. The defendant
    challenged the
    district court’s giving of a joint criminal conduct instruction regarding
    the Gourdie assault. 
    Id. In finding
    that the jury was properly instructed,
    we emphasized that the second assault was a joint crime, without
    9The   problem in Smith is not present here. In that case, there were not two
    separate crimes, just one—the shooting of the deputy by the cooccupant of Smith’s
    vehicle. See 
    Smith, 739 N.W.2d at 294
    . Smith handed the gun to him but did not shoot
    at the deputy himself. 
    Id. at 291.
                                               19
    addressing whether the first assault was a joint crime. See 
    id. at 849.
    However, under our more recent cases like Smith and Rodriguez, the first
    crime must be a joint one to support a joint criminal conduct theory and
    to prevent that theory from simply swallowing aiding and abetting
    liability.
    At oral argument before us, the State offered a different wrinkle to
    sustain its joint criminal conduct theory.              The State asserted that a
    group decision to surround Daughenbaugh, which would have put
    Daughenbaugh         in   fear    of   immediate,      painful     physical     contact,
    constituted the first assault and therefore the first crime. See Iowa Code
    § 708.1(2) (defining assault). There are a couple of problems with this
    formulation of joint criminal conduct. For one thing, we doubt that our
    unit-of-prosecution precedents allow it. We question whether putting a
    victim in fear of being hit can be treated as a separate assault from the
    act of hitting that same victim shortly thereafter. See State v. Velez, 
    829 N.W.2d 572
    , 579–84 (Iowa 2013) (discussing whether a factual basis
    existed for two separate counts under Iowa Code section 708.4(1)). This
    would effectively transform many, if not most, assault cases into double-
    assault cases. See 
    id. at 588
    (Wiggins, J., dissenting) (cautioning against
    “convicting on voluminous and stacked charges”).                     In addition, the
    State’s oral argument theory was not presented at trial. 10
    10The State gave the following explanation of joint criminal conduct to the jury in
    closing argument:
    Instruction Number 21 is what is commonly referred to as joint
    criminal conduct, and what that contemplates is that an individual in
    Mr. Tyler’s position, the defendant, committed a crime, assault, attacking
    Mr. Daughenbaugh, striking him in the head, and that he and/or others
    committed what could arguably be viewed as a second crime, in this case
    murder, the stomping, kicking, and jumping on Mr. Daughenbaugh, and
    that the defendant, Mr. Tyler, could have reasonably expected this
    20
    D.    The Need for a New Trial.                Having found that the joint
    criminal conduct theory was not supported by the evidence and should
    not have been submitted to the jury, we must reverse Tyler’s conviction
    and remand for a new trial. As in Smith, “we have no way of knowing
    whether the jury found [the defendant] guilty . . . as a principal, an aider
    and abettor, or under the theory of joint criminal conduct.”                     
    See 739 N.W.2d at 295
    (reversing for a new trial where the joint criminal conduct
    theory should not have been submitted).
    The State cites to Griffin v. United States, 
    502 U.S. 46
    , 56, 
    112 S. Ct. 466
    , 472, 
    116 L. Ed. 2d 371
    , 380 (1991), for the proposition that a
    general verdict need not be reversed “because one of the possible bases of
    conviction was . . . unsupported by sufficient evidence.”                     The Court
    explained,
    Jurors are not generally equipped to determine whether a
    particular theory of conviction submitted to them is contrary to
    law—whether, for example, the action in question is protected by
    the Constitution, is time barred, or fails to come within the
    statutory definition of the crime. When, therefore, jurors have
    been left the option of relying upon a legally inadequate theory,
    there is no reason to think that their own intelligence and expertise
    will save them from that error. Quite the opposite is true, however,
    when they have been left the option of relying upon a factually
    inadequate theory, since jurors are well equipped to analyze the
    evidence . . . .
    
    Id. at 59,
    112 S. Ct. at 
    474, 116 L. Ed. 2d at 382
    –83.
    Griffin of course is binding on us to the extent it describes a federal
    due process minimum. However, the Griffin Court also stated that “if the
    _________________________________
    different crime to have occurred and have been committed in furtherance
    of his assault.
    Tyler responded in his closing argument that the first assault could not
    be the basis for joint criminal conduct because “there is no evidence that that
    first assault . . . involved anyone other than Kent Tyler.” Based on our review of
    the record, the jury never considered the possibility that the forming of the circle
    around Daughenbaugh constituted an assault.
    21
    evidence is insufficient to support an alternative legal theory of liability,
    it would generally be preferable for the court to give an instruction
    removing that theory from the jury’s consideration.” 
    Id. at 60,
    112 S. Ct.
    at 
    474, 116 L. Ed. 2d at 383
    .               And, as a matter of sound judicial
    administration, we have decided to go in a different direction in Iowa. In
    State v. Hogrefe, 
    557 N.W.2d 871
    , 881 (Iowa 1996), we reversed for a new
    trial when the jury returned a general verdict and not all the theories
    were supported by substantial evidence. We explained,
    What we have then is a marshalling instruction that
    allows the jury to consider three theories of culpability, only
    one . . . of which is supported by the evidence. With a
    general verdict of guilty, we have no way of determining
    which theory the jury accepted.          Because there was
    insufficient evidence to support an instruction to consider all
    the checks, the district court erred in giving the marshalling
    instruction.
    Id.; see also State v. Thorndike, 
    860 N.W.2d 316
    , 321 (Iowa 2015)
    (collecting cases).       This is our precedent and we see no reason to
    overturn it. 11
    IV. Admission of B.B.’s Testimony Regarding Fighting.
    Because this issue can be expected to come up on retrial, we
    address Tyler’s argument that the district court should not have
    admitted B.B.’s testimony on Tyler’s prior involvement in fighting in
    11We  are not alone. Notwithstanding Griffin, supreme courts in a number of
    other states have declined to affirm general verdicts of guilt where at least one of the
    theories given to the jury was not supported by sufficient evidence. See, e.g., State v.
    Jones, 
    29 P.3d 351
    , 373 (Haw. 2001); State v. Owen, No. 102,814, 
    2015 WL 1309978
    ,
    at *5–6 (Kan. Mar. 13, 2015); Commonwealth v. Plunkett,

    1996); State v. Adams, ___ N.E.3d ___, ___, No. 2011–1978, 
    2015 WL 5728458
    , at *45

    supreme courts that follow Griffin).
    22
    concert with Williams, Russell, and Shorter. 12              When Tyler objected to
    this testimony, the court held a hearing outside the presence of the jury.
    An offer of proof took place during which B.B. was examined and cross-
    examined. B.B. was asked to leave the courtroom and the district court
    asked Tyler to argue his objection and the State to argue its theory of
    admissibility. Thereafter, the district court found as follows:
    Well, under any of the three theories of the
    prosecution, the State has the burden to prove the
    knowledge and intent of the defendant, and knowledge is
    particularly important under the theory of aiding and
    abetting and joint criminal conduct. The State has the
    burden to prove under the facts of this particular case that
    not only did the defendant strike the first blow but he knew
    or could reasonably expect that the first blow would be
    followed by assaults of his accomplices.
    The witness who was present observing all of this
    knew based on her prior experience with this defendant and
    his brother, Leprese [Williams], just that same summer at a
    similar party under similar circumstances that there was
    going to be a fight based on what she was observing. That is
    very strong evidence, it seems to me, that the defendant
    himself knew or could reasonably expect that by confronting
    this person who turned out to be the victim and allegedly, at
    least at this point, striking the first blow that a fight was
    going to follow. A person intends the natural consequences
    of their act.
    So the evidence in my mind at least is highly probative
    of the defendant’s knowledge and intent. The evidence is not
    being offered to show that the defendant has a bad character
    and acted in conformity therewith on this particular
    occasion. The evidence is being offered to show proof of
    12In  the offer of proof, B.B. testified she had seen Tyler, Williams, Russell, and
    Shorter hang out together and had seen Tyler and Williams fight people and Russell
    and Shorter fight people, but not all four of them fight at once. According to B.B.’s offer
    of proof testimony, the incident that she witnessed involving Tyler and his half-brother
    Williams occurred in the summer of 2013, shortly before Daughenbaugh was killed.
    Before the jury, B.B. simply testified that when she saw the group including Tyler,
    Williams, Russell, and Shorter surround Daughenbaugh, she wanted “to get out of
    there” because she had seen these people engage in fighting before and “didn’t want to
    be a part of it.” We believe any differences in the offer of proof record and the trial
    record are not material to our evaluation of the district court’s evidentiary ruling.
    23
    motive, opportunity, intent, preparation, plan, knowledge,
    identity, and absence of mistake or accident, and that is
    allowed under rule 404(b).
    There is a question whether the probative value of this
    evidence would be substantially outweighed by the danger of
    unfair prejudice to the defendant or confusion of the issues
    or misleading the jury or by considerations of undue delay or
    waste of time or the needless presentation of cumulative
    evidence under Rule 5.403. But performing that balance,
    the Court thinks that the—or finds that the substantial
    probative value of this evidence on an essential element of
    the charge is not substantially outweighed by the danger of
    unfair prejudice or the other considerations of the rule.
    This evidence is available to the State. There is a
    witness who was present at the scene of the crime who had
    knowledge and a feeling that something like this was going
    to happen, and it did. If she knew that based on what she
    knew of this defendant, one could reasonably infer that the
    defendant knew it too. And so I believe this evidence is
    relevant under the rules and it is admissible, and the
    objections will be overruled.
    The district court did not abuse its discretion in this thorough and
    comprehensive ruling. Because the ruling is largely self-explanatory and
    consistent with our caselaw, 13 we add only a few observations. First, the
    13As   we have said,
    To be admissible, the prosecutor must articulate a noncharacter theory
    of relevance. The court then must determine whether the other crimes,
    wrongs, or acts evidence is relevant and material to a legitimate issue in
    the case, other than a general propensity to commit wrongful acts. If the
    court determines the evidence is relevant to a legitimate issue in dispute,
    the court must determine whether the probative value of the other
    crimes, wrongs, or acts evidence is substantially outweighed by the
    danger of unfair prejudice to the defendant. In determining whether the
    probative value of other crimes, wrongs, or acts evidence is substantially
    outweighed by the danger of unfair prejudice, the court should consider
    the need for the evidence in light of the issues and the
    other evidence available to the prosecution, whether there
    is clear proof the defendant committed the prior bad acts,
    the strength or weakness of the evidence on the relevant
    issue, and the degree to which the fact finder will be
    prompted to decide the case on an improper basis.
    If the evidence’s probative value is substantially outweighed by its unfair
    prejudice, it must be excluded.
    24
    evidence that Tyler struck Daughenbaugh first with a blow to the head
    was fairly strong, and the evidence that others in the surrounding crowd
    then stomped and kicked him to death was also fairly strong. Thus, it is
    less likely that this evidence would have served, or needed to serve, an
    improper “propensity” purpose—i.e., because Tyler fought before, he was
    fighting that night. At the same time, the State’s evidence was not as
    strong concerning the foreseeability to Tyler of others beating on
    Daughenbaugh once Tyler hit him.              B.B.’s testimony helped shore up
    that area of the State’s case. This is one legitimate use of other “bad
    acts” evidence—to prove the defendant’s knowledge and intent. See Iowa
    R. Evid. 5.404(b); State v. Nelson, 
    791 N.W.2d 414
    , 425 (Iowa 2010). We
    affirm the district court on this point.
    V. Conclusion.
    For the foregoing reasons, we vacate the decision of the court of
    appeals. We reverse Tyler’s conviction and sentence and remand for a
    new trial in accordance with this opinion.
    DECISION OF COURT OF APPEALS VACATED; DISTRICT
    COURT JUDGMENT AFFIRMED IN PART AND REVERSED IN PART
    AND CASE REMANDED.
