Q

Malice Aforethought

A
  • 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)

Q

Deliberate and Premeditated First Degree Murder

A
  • 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

Q

First Degree Felony Murder

A
  • 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)

Q

Limitations on Felony Murder Liability

A
  • 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

Q

Felony Murder - Theories of Liability

A
  • 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

Q

Voluntary Manslaughter - Provocation

A

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

Q

Murder vs. Voluntary Manslaughter

A
  • “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)

Q

Causation

A

Def’s conduct must be both:
- cause-in-fact of victim’s death (“but for” cause)
- proximate cause of victim’s death (death = natural + probable consequence)
-> superseding factors often break chain of proximate causation

17
Q

Rules of Causation

A
  • an act that hastens an inevitable result is still the legal cause of that result
  • simultaneous acts of two or more persons may be independently sufficient causes of a single result
  • victim’s preexisting weakness or fragility, even if unforeseeable, doesn’t break chain of causation
18
Q

Causation - Limitations

A
  • year and a day rule
  • intervening acts
19
Q

Causation - Year and a Day Rule

A
  • traditionally, for def to be liable for homicide, the death of the victim must occur w/in one year + one day from infliction of the injury or the wound
  • BUT most states that have reviewed this rule have abolished it
20
Q

Causation - Intervening Acts

A
  • generally, an intervening act shields def from liability if the act is a coincidence or is outside the foreseeable sphere of risk created by def
  • BUT third party’s negligent medical care + victim’s refusal of medical treatment for religious reasons both count as foreseeable risks -> def would still be liable
