Question 1
Angered because the victim owed him money, Dane beat the victim repeatedly with a baseball bat, intending to injure him but not to kill him. The victim died from his injuries. The state charged Dane with felony murder, relying on aggravated battery as the underlying felony.
Which of the following issues is most significant in evaluating the felony murder charge against Dane?
- Whether aggravated battery is an inherently dangerous felony that can support a felony murder charge.
- Whether Dane's intent to injure the victim can satisfy the mental state required for murder.
- Whether the felony of aggravated battery is independent of the killing or merges with it. (correct answer)
- Whether Dane's beating of the victim was the actual cause of the victim's death.
Explanation: Whenever you see felony murder with an underlying crime that is itself an attack on the victim, your first thought should be merger. Felony murder requires a predicate felony independent of the killing. If the underlying felony is an assaultive crime against the same victim—like aggravated battery—it merges into the homicide and cannot support the charge. Here, Dane's aggravated battery was the very beating that killed the victim, so the most significant issue is whether that felony is independent of the killing or merges with it.
The inherent-dangerousness choice is a trap: even if aggravated battery is inherently dangerous, the merger doctrine still bars using it as the predicate felony. The intent-to-injure choice misses the point: felony murder does not require intent to kill, but the state must have a valid underlying felony. The actual-cause choice is not the crux; the beating plainly caused death, and causation alone does not solve the merger problem.
Study tip: remember that assaultive felonies merge—if the predicate felony is the same conduct as the killing, it cannot support felony murder.
Question 2
Jamal and Tyrell robbed a convenience store at gunpoint. They fled on foot and, after several blocks, entered Tyrell's apartment and locked the door. Believing they had escaped, they split the cash and went to sleep. Three hours later, police surrounded the apartment. When officers announced their presence, Tyrell fired a shotgun through the door, killing one officer. Jamal is charged with felony murder for the officer's death. The jurisdiction's felony-murder statute provides:
'A person is guilty of felony murder when, in the commission of, or in immediate flight from the commission of, robbery, burglary, arson, rape, or kidnapping, he or another participant causes the death of a person. For purposes of this section, the commission of the felony and immediate flight therefrom continue until the participants have reached a place of temporary safety; once a participant has reached a place of temporary safety, the felony is complete and this section no longer applies.'
Which of the following is Jamal's best argument against felony-murder liability?
- The felony had ended because the participants had reached a place of temporary safety before the shooting occurred. (correct answer)
- Jamal was asleep and had no prior knowledge of, or participation in, Tyrell's decision to shoot at the officers.
- The officer's death was not reasonably foreseeable because the police did not arrive until three hours after the robbery.
- Tyrell's shooting was not in furtherance of the robbery because the cash had already been divided and the participants were no longer escaping.
Explanation: Whenever you see a felony-murder question, first ask whether the killing occurred during the enumerated felony or immediate flight. Here, the statute gives a specific cutoff: the felony continues only until the participants reach a place of temporary safety; once they do, the felony-murder statute no longer applies. Jamal's best argument is that he and Tyrell entered Tyrell's apartment, locked the door, divided the cash, and slept for three hours before police arrived — so they had already reached a place of temporary safety and the robbery/fleeing was complete. That makes the officer's death outside the statute's reach.
The argument that Jamal was asleep and had no prior knowledge of Tyrell's decision fails because felony murder does not require every participant to know about or join the killing; a participant can be liable for a co-felon's killing during the felony. The argument that the death was not reasonably foreseeable because police arrived three hours later misses the point — felony murder is not primarily about foreseeability, and the statute's end is temporary safety, not a time limit. Finally, the claim that Tyrell's shooting was not in furtherance of the robbery because the cash was already divided is weak: dividing the cash is not the statutory endpoint, and shooting at officers could still be seen as trying to avoid apprehension.
Study tip: on felony-murder questions, always check any statutory definition of when the felony ends. "Temporary safety" is a common cutoff, and once safety is reached, later killings are separate crimes, not felony murder.
Question 3
Marcus and Ty robbed a convenience store at gunpoint. As they ran to their getaway car, a police officer who had responded to the alarm fired at them. One bullet missed the men and struck and killed a customer standing near the store entrance. The state charged Marcus and Ty with felony murder for the customer's death.
Which of the following issues is most significant in determining whether Marcus and Ty can be convicted of felony murder?
- Whether the death may be attributed to Marcus and Ty even though the officer fired the fatal shot. (correct answer)
- Whether Marcus and Ty intended to kill the customer or only to cause serious bodily injury.
- Whether the police officer's use of deadly force was lawful under the circumstances.
- Whether the robbery had been completed before the police officer fired the shot.
Explanation: Whenever you see a felony-murder question, your first instinct should be to focus on causation and the underlying felony, not on the killer's intent. Here, Marcus and Ty committed robbery, and a customer died—but the fatal shot was fired by a police officer. The most significant issue is whether the death may be attributed to Marcus and Ty even though the officer fired the fatal shot. Felony murder does not require the defendants to be the actual shooters; a defendant is liable for a death that is a foreseeable consequence of the felony. A police officer firing at fleeing armed robbers is a foreseeable risk, so the death can be attributed to them if causation is established.
The intent-based choices—whether they intended to kill the customer or only to cause serious bodily injury—are traps. Felony murder does not require intent to kill; malice is implied from the intent to commit the underlying felony. The lawfulness of the officer's use of deadly force is also not the central question: even if the officer acted wrongly, the defendants may still be liable if their felony foreseeably set the deadly chain in motion. Finally, whether the robbery had been completed before the officer fired is less significant because flight from a robbery is generally treated as part of the same criminal transaction, and the shooting occurred while they were escaping.
Study tip: in felony murder, ask "Who caused the death, and was that death foreseeable from the felony?" That separates the real issue from distracting facts about intent or third-party conduct.
Question 4
Nina and an accomplice robbed a convenience store at gunpoint. They drove to the accomplice's apartment and divided the stolen cash. About an hour later, the store clerk, who had followed the getaway car, knocked on the apartment door. The accomplice opened the door and shot and killed the clerk. The state charged Nina with felony murder for the clerk's death.
Which of the following issues is most significant in determining whether Nina is guilty of felony murder?
- Whether the accomplice intended to kill the clerk when he opened the apartment door.
- Whether the killing occurred during the commission of the robbery or after the robbery had ended. (correct answer)
- Whether the clerk's death was caused by the accomplice rather than by Nina.
- Whether robbery is an inherently dangerous felony that can support a felony murder conviction.
Explanation: Whenever you see a felony murder question, the central issue is whether the killing occurred "in the commission or attempted commission" of the underlying felony. That phrase has a temporal limit: the felony includes immediate flight, but ends once the felons reach a place of temporary safety. Here, Nina and the accomplice robbed the store, drove to the apartment, and divided the cash. That division indicates the robbery had already concluded. An hour later, the accomplice shot the clerk—an independent event, not part of the robbery. So Nina likely is not guilty of felony murder.
The choice asking whether the killing occurred during the robbery or after it ended is the most significant issue because it directly tests this temporal requirement. The choice about whether the accomplice intended to kill is a trap: felony murder does not require intent to kill, only intent to commit the underlying felony. The choice about whether the accomplice rather than Nina caused the death misses the point—during a felony, all participants are liable for deaths caused by co-felons, so causation by the accomplice would not shield Nina. Finally, the choice about whether robbery is an inherently dangerous felony is true—robbery is a classic inherently dangerous felony—but that fact is not disputed here; the timing is.
Study tip: on any felony murder question, map the timeline. Ask yourself: did the killing happen during the felony or immediate flight, or after the felons reached safety? Once they reach a place of temporary safety, the felony ends—and so does felony murder liability.
Question 5
During a New Year's Eve celebration in a crowded street, Sora fired a handgun into the air. A bullet struck and killed a woman several blocks away. Sora is charged with second-degree murder.
Which additional fact would be most important in determining whether Sora is guilty of murder rather than a lesser offense?
- Whether Sora knew that the bullet could travel several blocks and strike someone. (correct answer)
- Whether Sora had been drinking alcohol earlier that evening.
- Whether Sora intended to kill the woman when he fired the gun.
- Whether Sora fired the gun to celebrate rather than out of anger.
Explanation: This question tests malice aforethought. Murder requires more than careless or even reckless behavior; for a killing to be murder, the defendant must act with a culpable mental state—such as intent to kill or, as here, conscious disregard of an extreme risk to human life. So the most important fact is whether Sora knew the bullet could travel several blocks and strike someone. If he knew, firing into a crowded street is depraved-heart murder: he consciously disregarded a substantial and unjustifiable risk. If he did not know, the killing is more likely involuntary manslaughter or criminal negligence.
Whether Sora had been drinking earlier is not independently decisive. Voluntary intoxication can affect perception, but it does not establish the conscious disregard needed for murder, and it is not a general defense to a malice offense. Whether Sora intended to kill the woman when he fired would make this an intentional murder, but actual intent is not required for second-degree murder—a depraved-heart killing can be murder without any desire to kill. This choice is a trap if you assume murder always requires intent to kill. Whether Sora fired to celebrate rather than out of anger addresses motive, not mental state. Celebration can still be murder if he knowingly endangered others.
When you see murder versus manslaughter, separate motive from malice. Focus on what Sora knew and consciously accepted. Knowing creation of an extreme risk of death is malice; lesser awareness means a lesser offense.
Question 6
Tess drank nearly a full bottle of whiskey at a party. After an argument with the victim, Tess went to her car, retrieved a handgun, returned to the party, and shot the victim three times. The victim died. Tess is charged with first-degree murder.
Which of the following issues is most significant in determining whether Tess is guilty of first-degree murder rather than second-degree murder?
- Whether Tess's intoxication prevented her from forming the intent to kill the victim.
- Whether the argument with the victim provoked Tess into a heat of passion.
- Whether Tess was so intoxicated that she was temporarily insane at the time of the shooting.
- Whether Tess's intoxication negated the premeditation required for first-degree murder. (correct answer)
Explanation: When you see a murder question asking about first-degree versus second-degree, the dividing line is premeditation: first-degree murder requires a deliberate, premeditated killing, while second-degree murder requires malice but no premeditation. Voluntary intoxication rarely excuses a killing, but it can matter because it may negate a specific-intent element. The most significant issue here is whether Tess's intoxication negated the premeditation required for first-degree murder. If she was too intoxicated to form a deliberate plan to shoot the victim, she cannot be convicted of first-degree murder; she could still be guilty of second-degree murder if she acted with malice.
The choice about whether her intoxication prevented her from forming the intent to kill is less decisive because intent to kill is not the element that separates first-degree from second-degree—a killing can be intentional but still unpremeditated. The heat-of-passion choice is also not the issue: provocation, if established, would reduce murder to voluntary manslaughter, not distinguish first-degree from second-degree. The temporary-insanity choice is a trap: voluntary intoxication is not treated as insanity for this purpose, and it would not explain why the crime is second-degree rather than first-degree. Remember: on a first-degree versus second-degree murder question, focus on premeditation and deliberation, not on general intent or provocation.
Question 7
Rafael, a convicted felon, was stopped for a traffic violation. Police found a loaded semiautomatic handgun under the driver's seat. While officers were handcuffing him, Rafael broke free, grabbed the handgun, and fired wildly at the officers; a bullet struck and killed a bystander. Rafael is charged with felony murder, with felon in possession of a firearm as the predicate felony. The felony-murder statute applies to a death caused during the commission of 'any felony that is inherently dangerous.' In People v. Ellison, the state supreme court held:
'In determining whether a felony is inherently dangerous for purposes of felony murder, the felony must be evaluated in the abstract, by its statutory definition, and not by the particular facts of the case. A felony is inherently dangerous only if, by its very nature, it poses a substantial risk that death will result. Under this standard, felon in possession of a firearm is not inherently dangerous, because the mere possession of a firearm, without more, does not by its nature create a substantial risk of death.'
Which of the following is Rafael's best argument on appeal from the felony-murder conviction?
- The killing did not occur during the commission of the felon-in-possession offense because Rafael's possession ended when he was arrested.
- The predicate felony of felon in possession of a firearm is not inherently dangerous when evaluated in the abstract, as Ellison requires. (correct answer)
- The bystander's death was not a reasonably foreseeable consequence of the offense of felon in possession of a firearm.
- Felony murder cannot be predicated on an offense that is not specifically enumerated in the felony-murder statute, such as felon in possession of a firearm.
Explanation: Whenever you see a felony-murder question, first identify the predicate felony and the jurisdiction's inherent-danger test. Here, Ellison controls: you must evaluate the felony in the abstract, not by the defendant's particular conduct. That is why Rafael's best argument is that felon in possession of a firearm is not inherently dangerous when evaluated in the abstract. Under Ellison, mere possession of a firearm does not, by its very nature, create a substantial risk of death. The fact that Rafael actually grabbed the gun and fired is exactly the kind of particular-facts evidence Ellison says you must ignore. So the felony-murder conviction cannot stand.
The argument that the killing did not occur during the commission because possession ended at arrest is weaker: Rafael grabbed the gun and fired, so his possession plainly continued, and felony murder can reach deaths during resistance or flight. The argument that the death was not a reasonably foreseeable consequence of the offense misstates the test—inherent dangerousness is not about particular foreseeability but abstract risk. Finally, there is no requirement that the predicate felony be specifically enumerated in the felony-murder statute; the statute covers "any felony that is inherently dangerous," so a lack of enumeration is not a defense. The key lesson: when a state evaluates predicates "in the abstract," your brief must focus on the statutory definition of the crime, not the violent facts of what happened.
Question 8
At a bar, the victim loudly taunted Reid, calling him a coward and mocking Reid's recently deceased brother. Reid, who had been drinking, became enraged, immediately pulled out a knife, and stabbed the victim, who died. Reid is charged with murder.
Which of the following issues is most significant in determining whether Reid is guilty of murder rather than voluntary manslaughter?
- Whether Reid's drinking caused him to lose control of his actions.
- Whether Reid reasonably believed the victim was about to attack him.
- Whether Reid intended to stab the victim when he pulled out the knife.
- Whether the victim's taunts were legally adequate provocation for the killing. (correct answer)
Explanation: Whenever you see a question distinguishing murder from voluntary manslaughter, the central issue is whether the killing occurred in the heat of passion after legally adequate provocation. Voluntary manslaughter requires both a subjective loss of self-control and an objectively adequate provocation — something that would inflame a reasonable person. Here, the victim's taunts are the only possible provocation, so the most significant issue is whether those words qualify.
They do not. At common law, mere words — even vicious insults or mocking a deceased family member — are not legally adequate provocation. Adequate provocation typically involves things like a serious physical assault, mutual combat, or discovering a spouse in adultery. Because Reid's reaction was triggered only by taunts, the provocation is insufficient, and the killing remains murder.
The other choices miss the mark. Reid's drinking may explain his loss of control, but voluntary intoxication does not reduce murder to manslaughter. Whether Reid reasonably believed the victim was about to attack him would matter for self-defense, but there is no evidence of an imminent threat. And whether Reid intended to stab the victim is not the dividing line here — he likely did intend to stab, and provocation is what could reduce that intentional killing to manslaughter.
Study tip: whenever an answer choice mentions "insults" or "words," remember the common-law rule — words alone are almost never adequate provocation.
Question 9
Marcus arrived home early and found his wife Lena in the living room with Victor. Lena and Victor were fully clothed but locked in a passionate embrace, kissing and touching; there was no evidence they had engaged in sexual intercourse. Enraged, Marcus grabbed a fireplace poker and struck Victor, killing him. Marcus is charged with murder. The jurisdiction's homicide statute provides:
'A killing that would otherwise be murder is voluntary manslaughter if committed upon a sudden quarrel or heat of passion, provided that the provocation was legally adequate. Adequate provocation is limited to: (1) a serious battery upon the defendant; (2) mutual combat; or (3) the discovery by the defendant of his or her spouse in the act of sexual intercourse with another person. Mere words, gestures, or other non-violent acts, however offensive or insulting, do not constitute adequate provocation.'
Should the court grant Marcus's request for a voluntary-manslaughter instruction?
- Yes, because Marcus discovered his spouse in the act of sexual intercourse with Victor, which the statute expressly makes adequate provocation.
- Yes, because the circumstances would cause a reasonable person to lose self-control, and reasonableness is the standard for adequate provocation.
- No, because Marcus had sufficient time between his discovery and the killing to cool off, so he did not act in the heat of passion.
- No, because the embrace was a non-violent act that does not fall within any statutory category of adequate provocation. (correct answer)
Explanation: Whenever a homicide question provides a statutory definition of adequate provocation, your job is to apply that statute strictly, not the broader common-law heat-of-passion doctrine. The statute here limits adequate provocation to three categories: serious battery, mutual combat, or discovering your spouse in the act of sexual intercourse. Marcus saw Lena and Victor kissing and touching, fully clothed, with no evidence of intercourse. That is not "the act of sexual intercourse," so it falls outside the statute. The court should deny the instruction because the embrace is a non-violent act that does not fit any listed category.
The choice claiming Marcus discovered his spouse in the act of sexual intercourse misreads the facts: passionate embrace is not intercourse. The choice invoking a reasonable-person standard reflects a common-law test, but the statute deliberately replaces that general standard with a closed list. The choice about cooling time also misses the point: even if Marcus acted instantly and in genuine heat of passion, the statute still requires legally adequate provocation, and this provocation is not adequate. Finally, although the language "non-violent acts" might seem harsh, the statute explicitly says mere words, gestures, or other non-violent acts do not qualify, so the denial is correct.
On exam day, read statutory provocation definitions as exhaustive. If the facts describe a category not listed—even one that feels sympathetic—do not stretch the statute. The question is testing whether you can resist common-law instincts and apply the legislature's precise limits.
Question 10
Dax and Cole robbed a bank at gunpoint. As they were leaving, Cole raised his gun toward a police officer; the officer fired and killed Cole. Dax, who had not fired his weapon, was charged with first-degree felony murder for Cole's death. The jurisdiction's felony-murder statute provides:
'Any person who, acting with one or more other persons, commits or attempts to commit robbery, burglary, arson, rape, or kidnapping, and who in the course of or in furtherance of such crime, or in immediate flight therefrom, causes the death of any person, is guilty of murder in the first degree. For purposes of this section, a person causes a death when his conduct is a proximate cause of the death, including when the death is inflicted by a person other than a participant in the crime, if the death was a reasonably foreseeable consequence of the crime or of a participant's conduct in the course of the crime.'
Is Dax guilty of felony murder for Cole's death?
- No, because the statute requires that a participant in the felony cause the death, and Cole was killed by a police officer rather than by Dax or another participant.
- No, because Cole's act of raising his gun toward the officer was an independent intervening cause that broke the chain of proximate causation between the robbery and his death.
- Yes, because Cole's death was a reasonably foreseeable consequence of the armed robbery, and the statute expressly covers deaths inflicted by non-participants. (correct answer)
- Yes, because the statute imposes strict liability on every participant for any death occurring during the robbery, regardless of foreseeability or who fired the shot.
Explanation: When a felony-murder statute includes a proximate-cause clause like this one, the central question is not who pulled the trigger but whether the death was a foreseeable result of the felony and its circumstances. Here, the statute explicitly covers deaths "inflicted by a person other than a participant" if the death was a "reasonably foreseeable consequence" of the crime. An armed robbery creates a deadly confrontation risk; when Cole raised his gun at the officer, the officer's lethal response was a foreseeable consequence of the robbery and Cole's conduct. Dax, as a participant in the robbery, is therefore guilty of first-degree felony murder for Cole's death.
The answer that says "no, because the statute requires that a participant cause the death" misreads the statute—it expressly includes non-participant inflictions. The claim that Cole's act was an "independent intervening cause" also fails: a victim's or officer's foreseeable self-defense response does not break causation; it is exactly the type of risk felony-murder law covers. The strict-liability answer overstates: the statute does not impose liability "regardless of foreseeability"; it requires proximate cause and reasonable foreseeability.
So when you see felony murder, immediately check whether the statute includes deaths caused by non-participants and whether the death was foreseeable from the felony's dangerous circumstances. That combination drives the answer.
Question 11
At a party in her apartment, Petra pointed a handgun at her friend Owen as a joke, saying 'Don't make me shoot you.' Petra believed the gun was unloaded; she had not checked it since a guest had been handling it earlier. The gun fired, killing Owen. Petra is charged with murder. In State v. Hoffman, the state supreme court held:
'Depraved-heart murder requires that the defendant actually be aware of a very high and substantial risk of death and consciously disregard that risk, demonstrating an extreme indifference to human life. A defendant who causes death through conduct that creates a risk of which he is unaware may be guilty of involuntary manslaughter if his conduct is criminally negligent, but he cannot be convicted of murder. Criminal negligence requires a gross deviation from the standard of care that a reasonable person would observe, but does not require that the defendant know of the risk.'
Under Hoffman, which conviction would be proper?
- Involuntary manslaughter, if her failure to check the gun was a gross deviation from reasonable care, because she was not actually aware of the risk. (correct answer)
- Murder, because Petra's failure to check whetherthe gun was loaded demonstrated an extreme indifference to human life and a conscious disregard of the risk.
- Murder, because pointing a loaded gun at another person creates a very high and substantial risk of death that any reasonable person would recognize.
- No crime, because Petra believed the gun was unloadedand therefore did not have the mental state required for any homicide offense.
Explanation: When you see a homicide question turning on risk, your first move is to separate what the defendant actually knew from what a reasonable person would have known. Depraved-heart murder demands actual awareness of a high risk and conscious disregard of it; involuntary manslaughter can rest on criminal negligence, which is judged objectively.
Here, Petra believed the gun was unloaded and had not checked it. Under Hoffman, that means she was not actually aware of the risk when she pointed the gun at Owen. So the murder theories fail. The proper result is involuntary manslaughter if her failure to check the gun was a gross deviation from what a reasonable person would do. That matches the choice saying "Involuntary manslaughter, if her failure to check the gun was a gross deviation from reasonable care, because she was not actually aware of the risk."
The remaining choices each misread Hoffman. "Murder, because Petra's failure to check whether the gun was loaded demonstrated extreme indifference" treats negligence as if it were conscious disregard—exactly what the court rejected. "Murder, because pointing a loaded gun creates a very high and substantial risk that any reasonable person would recognize" substitutes an objective standard for the required subjective awareness. Finally, "No crime, because Petra believed the gun was unloaded" is wrong: a mistaken belief in safety does not erase liability under a negligence theory; it just prevents murder.
Your takeaway: always ask whether the statute or case requires subjective awareness or only objective unreasonableness. If the defendant didn't know the risk, murder is out—but manslaughter may still be in.
Question 12
Darnell and Victor got into a fight at a bar. Darnell threw Victor to the ground and kicked him repeatedly in the head, intending to cause Victor serious bodily injury. Victor died from his injuries. Darnell is charged with first-degree felony murder, with aggravated battery as the predicate felony. The jurisdiction's felony-murder statute provides:
'A person is guilty of felony murder when, in the commission or attempted commission of any felony, he causes the death of another person. This section does not apply when the felony is an integral part of the homicide — that is, when the felony is assaultive in nature, because every homicide that is not justifiable or excusable necessarily includes an assault. A felony is assaultive in nature if the conduct constituting the felony is directed at the person of the victim and would, by itself, constitute a battery or an assault.'
Should the court grant Darnell's motion to dismiss the felony-murder count?
- No, because aggravated battery is a felony that is independent of the homicide and has its own statutory elements.
- No, because Darnell intended to cause serious bodily injury, and a killing with that intent is first-degree murder regardless of the predicate-felony rule.
- Yes, because aggravated battery is assaultive in nature and therefore merges with the homicide, leaving no independent predicate felony. (correct answer)
- Yes, because a killing during a bar fight is at most voluntary manslaughter since Darnell acted in a sudden quarrel.
Explanation: Whenever you see a felony-murder question, immediately ask: Is the predicate felony independent of the homicide, or is it assaultive and therefore part of the killing itself? That distinction drives the merger doctrine.
Here, Darnell is charged with felony murder using aggravated battery as the predicate felony. But the statute explicitly excludes felonies that are assaultive in nature — conduct directed at the victim that would itself constitute a battery or assault. Aggravated battery is exactly that: the blows to Victor's head are the same conduct that caused death. So the felony "merges" into the homicide, leaving no independent felony on which to base felony murder. The motion to dismiss should be granted, not denied.
The other choices miss this core point. The claim that aggravated battery is independent because it has its own statutory elements ignores the merger rule; a felony can have separate elements and still be assaultive in nature. The claim that intent to cause serious bodily injury makes it first-degree murder regardless of the predicate rule confuses degrees of murder with the felony-murder charge actually brought — malice may support intentional murder, but it does not cure a defective felony-murder count. And the suggestion that a bar fight is at most voluntary manslaughter ignores the facts: Darnell kicked a downed victim in the head intending serious bodily injury, which looks like murder, not sudden-quarrel manslaughter.
Study tip: on felony-murder questions, check first whether the predicate felony is assaultive — if it is, the merger doctrine kills the felony-murder count.
