Homicide Flashcards
Common Law Murder
Unlawful killing of a human being with malice aforethought
Malice Aforethought: intent to kill, intent to inflict great bodily injury, reckless indifference, intent to commit a felony
Statutory Murders
First Degree, Second Degree, Felony Murder, Manslaughter
First Degree Murder versus Second Degree
Default second degree unless premeditated and deliberate or a statute provides otherwise
How is second degree murder classified?
Usually as depraved heart killing (done with reckless indifference to an unjustifiably high risk to human life) or any murder not classified as first degree
Felony Murder
Any death (even accidental) caused in the commission of or in an attempt to commit a felony is murder. Malice is implied from the intent to commit the underlying felony
At common law, this includes felonies like burglary, arson, rape, but statutes today have created many more felonies
Felony Murder Limitations
- The defendant must have committed or attempted to commit the underlying felony
- The felony must be distinct from the killing itself
- Death must have been a foreseeable result of the felony
- The death must have been caused before the defendant’s “immediate flight” from the felony ended
- In most jurisdictions, the defendant is not liable for felony murder when a co-felon is killed by victim or police
Felony Murder: Proximate Cause vs. Agency Theory
Proximate Cause Theory: felons liable for deaths caused by someone other than co-felon
Agency Theory: killing must be committed by a felon or their “agent”
Voluntary Manslaughter
Voluntary manslaughter is a killing that would be murder but for the existence of adequate provocation
VM: When is provocation adequate?
- It was a provocation that would arouse sudden and intense passion of an ordinary person
- The defendant was in fact provoked
- There was not sufficient time between provocation and killing and
- The defendant in fact did not cool off
Imperfect Self Defense
Some states recognize an “imperfect self-defense” doctrine under which murder may be reduced to manslaughter even though the defendant was at fault starting the altercation or the defendant unreasonably but honestly believed in the necessity of responding with deadly force
Involuntary Manslaughter Elements
A killing is involuntary manslaughter if it was committed:
With criminal negligence (or MPC recklessness) or
In some states, during the commission of the unlawful act
Causation Requirement
The defendant’s conduct must be both the cause-in-fact and the proximate cause of the victim’s death
Cause-In-Fact
A defendant’s conduct is the cause-in-fact of the result if the result would not have occurred “but for” the defendant’s conduct
Proximate Causation
A defendant’s conduct is the proximate cause of the result if the result is a natural and probable consequence of the conduct
Rules of Causation
An act that hastens an inevitable result is still the legal cause of that result.
Also, simultaneous acts of two or more persons may be independently sufficient causes of a single result
