What is Involuntary Manslaughter?
criminal negligence (typically)
Causing the death of another human being as a direct result of:
- an unlawful act in a reckless or grossly negligent manner, or
- a lawful act in a reckless or grossly negligent manner.
Define Murder
Common Law - the unlawful killing of a human being by another human being with malice aforethought
MPC - Criminal homicide constitutes murder when 1) committed purposely or knowingly; or 2) it is committed recklessly under circumstances manifesting extreme indifference to the value of human life. Recklessness presumed when engaged in or an accomplice of actual or attempted robbery, rape, arson, burglary, kidnapping or felonious escape.
Define Manslaughter
The unlawful killing of a human being by another human being without malice aforethought.
MPC - Criminal homicide that is 1) committed recklessly; or 2) a homicide which would otherwise be murder is committed under the influence of extreme mental or emotional disturbance for which there is reasonable explanation or excuse. Determined from the viewpoint of a person in the actor’s situation under the circumstances as he believes them to be.
What is Malice Aforethought
- Intent to kill (express malice) - all other forms are “implied malice”
- Intent to commit serious bodily injury - some jurisdictions do not recognize this as malice aforethought
- Depraved-heart murder
- Under circumstances showing “depraved mind” or “abandoned and malignant heart”
- Often understood as “extreme recklessness” - Felony-Murder Rule
What is voluntary manslaughter?
intentional murder is reduced to voluntary manslaughter because of:
- Provocation (heat of passion)
- Imperfect self defense
- Diminished capacity
What are the degrees of murder in common law?
- 2nd degree - the default for intentional murder
- 1st degree - requires something additional, typically “premeditation and deliberation”
No degrees in MPC
What is premeditation?
the killer must have reflected upon and thought about the killing in advance.
No particular length of time is required
What is deliberation?
refers to the quality of the accused’s thought process, a killing that is deliberate is one that is undertaken with a cool head; the killer actually considers whether he wants to go on with the killing
Define criminal homicide
MPC - purposely, knowingly, recklessly or negligently causing the death of another human being.
Bingham Case (premeditation)
Defendant raped and strangled victim. Trial court found 3-5 minutes it took to strangle the victim was enough time for defendant to deliberate. Supreme Court of Washington overturned.
Rule: Premeditation and deliberation must occur before the commencement of the act of killing to constitute 1st degree murder.
Gilbert Case (mercy killing)
Defendant shot and killed his wife who was severely ill and in extreme pain for a long period of time. He shot her to end her suffering.
Defendant stated he had a clear and deliberate process and thought about intentionally killing her for quite a while.
Court affirmed the conviction for 1st degree murder.
What four elements are required for provocation?
- The defendant acted in the heat of passion,
- The defendant was reasonably provoked into the heat of passion,
○ Passion was a result of adequate provocation - Defendant did not have reasonable opportunity to cool off, and
- Causal link between the provocation, passion, and homicide.
Carr case (provocation)
Defendant shot and killed victim when he saw them engaging in homosexual kissing on a trail. Attempted to show history of rejection by women.
Not adequate provocation sufficient to cause a reasonable person to become so impassioned as to be incapable of cool reflection. A reasonable person would have left the scene.
Rule: The victim’s actions on the day of the killing must lead directly to the killing. If there is no legally adequate provocation, then evidence of previous abusive history is not relevant nor admissible.
What is the MPC Extreme Mental or Emotional Disturbance Test?
- §210.3(1)(b) - a homicide that would otherwise be murder to be considered manslaughter when it is committed “under the influence of extreme mental or emotional disturbance for which there is reasonable explanation and excuse.”
- Extreme mental or emotional disturbance
○ Determined from the viewpoint of a person in the actor’s situation under the circumstances as he believes them to be. - Reasonable explanation or excuse.
What is the Casassa Test for emotional disturbance?
The determination whether there was reasonable explanation or excuse for a particular emotional disturbance should be made by viewing the subjective, internal situation in which the defendant found himself and the external circumstances as he perceived them at the time, however inaccurate that perception may have been, and assessing from that standpoint whether the explanation…for his emotional disturbance was reasonable, so as to entitle him to a reduction of the crime charged from murder to manslaughter.
• How did he perceive the situation
• Was his emotional disturbance reasonable based on that view (even if inaccurate)
