What are the facts?
Defendants participated in an armed robbery of a business, holding employees and the owner at gunpoint and compelling them to lie on the floor while money was taken. The robbery caused the owner—who suffered from severe, preexisting coronary artery disease—to experience acute fright and stress. Within a short time after the robbers fled (on the order of minutes), the owner suffered a fatal myocardial infarction. Medical testimony established that the emotional shock and stress of the robbery precipitated the heart attack, though his underlying heart disease significantly contributed to the fatality. The defendants were charged and convicted of first-degree murder under California's felony-murder statute, which designates killings committed in the perpetration of robbery as first-degree murder. On appeal, the defendants argued that the death was not foreseeable, that they had no intent to kill, that the victim's preexisting condition was an independent cause, and that the jury should have been instructed on lesser offenses rather than first-degree felony murder.
What is the legal issue?
Does the felony-murder rule impose first-degree murder liability when, during the commission of a robbery, the victim dies from a heart attack precipitated by fright and stress, notwithstanding the victim's preexisting heart condition and the unforeseeability of death?
What rule applies?
Under California Penal Code § 189, a killing committed in the perpetration of an enumerated felony, including robbery, is murder of the first degree. The felony-murder rule imputes malice as a matter of law and does not require proof that the death was intended, foreseen, or a natural and probable consequence. So long as the homicide is the direct causal result of the felony—i.e., the felony is a substantial factor contributing to the death—the felon is strictly liable for murder and takes the victim as he finds him.
What did the court hold?
Yes. The court affirmed the first-degree murder convictions, holding that the felony-murder rule applies because the robbery directly precipitated the victim's fatal heart attack, regardless of foreseeability or the victim's preexisting physical frailty.
What is the reasoning?
The court explained that the statutory felony-murder rule substitutes the malice element of murder with the commission of certain inherently dangerous felonies; deterrence and accountability policies justify strict liability for deaths occurring in the course of those felonies. Because robbery is an enumerated felony under § 189, the prosecution was not required to prove intent to kill or that death was a reasonably foreseeable consequence of the robbery. Instead, the dispositive question was causation: whether the felony proximately caused the death. On causation, the court found substantial evidence that the robbery-induced fright and stress precipitated the heart attack, even though the victim's severe coronary disease was a contributing condition. The felony need not be the sole or immediate cause; it suffices that it was a substantial factor in bringing about the death. The defendants "take the victim as they find him," and cannot escape liability because the victim was unusually susceptible. Nor is there a requirement that the death be a natural and probable consequence or objectively foreseeable under the felony-murder doctrine. The court also rejected arguments for lesser-included offense instructions, reasoning that the statutory framework classifies killings in the course of robbery as first-degree murder when causation is established. Finally, because the death occurred during the res gestae of the robbery (shortly after the robbers fled), temporal and transactional continuity was satisfied.
Why is this case significant?
People v. Stamp is a cornerstone case in criminal law teaching for two reasons. First, it exemplifies the breadth of the felony-murder rule in California as it existed at the time: strict liability for deaths proximately caused by enumerated felonies, with no foreseeability requirement and no need to prove malice or intent to kill. Second, it clarifies the causation floor for felony-murder—requiring a direct causal connection and embracing the eggshell victim principle in criminal homicide. The case is frequently used in exam problems to test students' understanding of felony-murder, causation, and the res gestae/escape phase of a felony. (Students should also be aware that California has since reformed aspects of felony-murder liability by statute, but Stamp remains historically and doctrinally important.)
Does felony-murder require that the death be foreseeable?
Not under People v. Stamp. For enumerated felonies like robbery, foreseeability is not an element; malice is imputed by statute. The only requirement is a causal nexus—the felony must be a substantial factor directly contributing to the death.
What if the victim had a serious preexisting condition that made death more likely?
Stamp applies the eggshell victim principle: felons take victims as they find them. A defendant remains liable if the felony precipitates the fatal result, even if an unusual frailty (such as severe heart disease) contributes to or accelerates death.
Must the felony be the sole cause of death?
No. The felony need not be the exclusive or immediate cause. It is sufficient that the felony was a substantial factor in bringing about the death. In Stamp, the robbery-induced fright precipitated the heart attack, satisfying causation despite significant underlying disease.
Does the felony-murder rule apply if the death occurs shortly after the felons flee?
Yes, if the death occurs within the res gestae of the felony. Stamp treats the felony as continuing through the escape phase until the perpetrators reach a place of temporary safety. The victim's death shortly after the robbers left was still part of the robbery's continuous transaction.
How does Stamp interact with modern reforms to felony-murder in California?
Stamp reflects the traditional breadth of felony-murder for enumerated felonies. Subsequent statutory reforms (e.g., changes enacted in 2018) narrowed felony-murder liability in some respects, especially for non-killers and non-major participants. Nonetheless, Stamp remains a key precedent on causation and the eggshell victim concept within felony-murder analysis.
Could the jury have been instructed on manslaughter instead of first-degree murder?
Under Stamp, no. Because Penal Code § 189 classifies a killing during robbery as first-degree murder upon proof of causation, lesser-included manslaughter instructions were not warranted on the facts presented.
