Homicide Flashcards
What are the two broad categories The classification of Homicide.
- Lawful Homicide – Justified killings (e.g., self-defense, war, executions).
- Unlawful Homicide – Criminal killings (e.g., murder and manslaughter).
What are the Elements of Criminal Homicide.
For a prosecutor to convict someone of criminal homicide, they must prove three elements:
- Actus Reus (Guilty Act)
- Mens Rea (Guilty Mind)
- Causation
Actus Reus (Guilty Act)
Mens Rea (Guilty Mind)
- The defendant must have had a criminal intent (mental state) when the act was committed.
- The different types of criminal homicide require different levels of intent:
o Intentional killing → Murder.
o Extreme recklessness → Depraved Heart Murder.
o Criminal negligence → Involuntary Manslaughter.
Causation
A defendant is only guilty of homicide if their actions directly/Actual or proximately caused the victim’s death.
What is Actual Cause (“But For” Test)
Re: Causation
Actual Cause (“But For” Test)
* The death would not have occurred but for the defendant’s actions.
* Example: A doctor removes a terminally ill patient’s life support, causing them to die sooner than expected. The doctor’s action is the actual cause.
What is Proximate Cause (“Legal Cause”)
- The death must be a foreseeable result of the defendant’s actions.
- If **something highly unusual **happens in between, it might break the chain of causation and relieve the defendant of liability.
Is the following a example of Proimate Cause
Jack punches Tom in the face. Tom falls, hits his head on a rock, and dies. Jack proximately caused Tom’s death because it was foreseeable that hitting his head could be fatal.
Yes ✅ Proximate Cause Example:
Is the following a example of Proimate Cause?
Alice pushes Bill into a pool. Bill swims safely to the edge but is struck by lightning and dies.
Alice did not proximately cause the death—the lightning strike was an unforeseeable intervening event.
❌ Not Proximate Cause Example:
MURDER (Homicide with Malice Aforethought)
Murder is the unlawful killing of a human being with malice aforethought.
Malice Aforethought (Four Types)
A person has malice aforethought if they:
- Intended to kill someone.
- Intended to cause serious bodily harm that resulted in death.
- Acted with extreme recklessness (“depraved heart murder”).
- Caused a death while committing a dangerous felony (“felony murder”).
FOUR TYPES OF COMMON LAW MURDER
- Intent-to-Kill Murder
- Intent-to-Cause-Serious-Bodily-Injury Murder
- Depraved-Heart Murder (Extreme Recklessness)
- Felony Murder
FOUR TYPES OF COMMON LAW MURDER
Intent-to-Kill Murder
- Definition: The defendant deliberately kills another person.
- Mens Rea: Specific intent to kill.
- Example:
o Jake buys a gun, waits outside for his enemy, and shoots him in the head. - Key Rule: Premeditation is required for first-degree murder (see degrees of murder below).
FOUR TYPES OF COMMON LAW MURDER
Intent-to-Cause-Serious-Bodily-Injury Murder
- Definition: The defendant intended serious harm, but not necessarily death, and the victim died as a result.
- Example:
o Jim swings a metal baseball bat at Bob’s head, causing a skull fracture. Bob later dies from brain swelling. - Key Rule: Even though Jim only meant to injure Bob, the death makes it murder.
FOUR TYPES OF COMMON LAW MURDER
Depraved-Heart Murder (Extreme Recklessness)
- Definition: The defendant acts with extreme indifference to human life.
- Mens Rea: Extreme recklessness (NOT intent to kill).
- Example:
o Matt fires a gun into a crowd for fun, and someone dies.
o A person drives 120 mph through a school zone and hits a pedestrian. - Key Rule: No intent to kill is needed—just recklessness so extreme that it shows disregard for human life.
FOUR TYPES OF COMMON LAW MURDER
Felony Murder
- Definition: A death occurs during the commission of a dangerous felony, and all felons are guilty of murder, even if they did not personally kill the victim.
- Key Felonies (“BARRK” Felonies):
o Burglary
o Arson
o Robbery
o Rape
o Kidnapping - Examples:
o A robber fires a warning shot and accidentally kills a store clerk → Felony Murder.
o A hostage dies from stress during a kidnapping → Felony Murder.
What are the degrees of Murder
MANSLAUGHTER (Homicide Without Malice)
- Voluntary Manslaughter (“Heat of Passion”)
- Involuntary Manslaughter
Voluntary Manslaughter (“Heat of Passion”)
- Definition: Intentional killing, but committed in the heat of passion due to adequate provocation.
- Example:
o John catches his wife cheating, immediately stabs her lover, and kills him. - Key Rule: If there was time to cool off, it becomes murder instead.
Involuntary Manslaughter
- Definition: Unintentional killing due to recklessness or criminal negligence.
- Types:
1. Criminally Negligent Manslaughter:
Example: A parent leaves a baby in a hot car, and the baby dies.
2. Unlawful Act (Misdemeanor) Manslaughter:
Example: A driver speeds through a school zone, hitting and killing a child.
