Homicide Flashcards
Common Law Murder
- unlawful killing of a human being with malice aforethought
- note that intentional use of deadly weapon authorized permissive inference of intent to kill
Malice Aforethought
- common law concept
Exists if there are no facts reducing the killing to voluntary manslaughter or excusing it (i.e. giving rise to a defense), + committed w/ one of the following states of mind:
- intent to kill
- intent t inflict great bodily injury
- reckless indifference to an unjustifiably high risk to human life (“abandoned and malignant heart” or “depraved heart”)
- intent to commit a felony (felony murder)
Statutory Modification of Common Law Classifications
- some jurisdictions divide murder into degrees (first + second) by statute
First Degree Murder
A murder = second degree murder UNLESS:
- deliberate + premeditated
- first degree felony murder
- certain statutorily specified circumstances are present (ex: some states make killing of a police officer automatically first degree murder)
Deliberate and Premeditated First Degree Murder
- if def made decision to kill in a cool + dispassionate manner + actually reflected on the idea of killing, even if only for a very brief period, it’s first degree murder
- def must’ve acted w/ intent or knowledge that their conduct would cause death
- may be negated by voluntary intoxication (since premeditation requires specific intent) -> means if def so intoxicated that couldn’t premeditate, highest degree of murder they can be convicted for = second or voluntary manslaughter
First Degree Felony Murder
- killing committed during the commission of a felony
- many states make it 1st degree only if the felony is one of certain enumerated ones (ex: burglary, arson, rape, robbery + kidnapping), but some don’t enumerate
- those that don’t enumerate sometimes just require that the felony be inherently dangerous to human life or dangerous to human life as committed
- note that this is the modern framework, but in general, any death, even accidental, caused in the commission of or in an attempt to commit a felony is murder (malice implied from intent to commit the felony)
Second Degree Murder
- usually “depraved heart killing”: killing done w/ reckless indifference to an unjustifiably high risk to human life
- OR just any murder that isn’t 1st degree
Limitations on Felony Murder Liability
- def must’ve committed or attempted to commit the underlying felony -> any defense that negates underlying offense will also be a defense for felony murder
- felony must be distinct from the killing itself (ex: aggravated battery that causes victim’s death can’t be source of killing for felony murder)
- death must’ve been foreseeable result of the felony
- death must’ve been cause before the defendant’s “immediate flight” from the felony ended (once def has reached “temporary safety”, subsequent deaths not felony murder)
- in most jurisdictions, def is NOT liable for felony murder when co-felon is killed as a result of resistance from felony victim or police
Felony Murder - Theories of Liability
- proximate cause theory says you’re liable for deaths of innocent victims even if they’re caused by someone other than a co-felon
- vs. agency theory says killing must be committed by felon or accomplice
Voluntary Manslaughter
- killing that would be murder but for the existence of adequate provocation
Voluntary Manslaughter - Provocation
Adequate only if:
- it was a provocation that would arouse sudden + intense passion in the mind of an ordinary person, causing them to lose self-control
- def was in fact provoked
- there not sufficient time between the provocation + the killing for passions of a reasonable person to cool; AND
- def in fact did not cool off between provocation + killing
- book notes make sure to evaluate all four
Murder vs. Voluntary Manslaughter
- “heat of passion” is NOT a DEFENSE to murder -> it just lowers the seriousness of the offense from murder to manslaughter
- SO if a q offers “not guilty because defendant acted in heat of passion” as an answer choice, it’s automatically wrong (heat of passion CANNOT negate guilt)
Imperfect Self-Defense
- recognized in some states
Allows murder to be reduced to manslaughter even though:
1) def was at fault in starting the altercation, OR
2) def unreasonably but honestly believed in necessity of responding w/ deadly force
Involuntary Manslaughter
- any killing committed w/ criminal negligence (or “recklessness” under MPC)
- OR in some states, during commission of unlawful act not included under felony murder (ex: misdemeanor or a lesser felony)
Involuntary Manslaughter vs. Abandoned and Malignant Heart Murder
- abandoned + maligant heart murder at common law involves HIGH risk of death, vs. involuntary manslaughter based on recklessness only requires SUBSTANTIAL risk
