California Voluntary Manslaughter Laws
Homicide, the unlawful killing of a human being, may result in a criminal charge of murder or manslaughter. In a murder case, the prosecutor must establish the defendant's "malice aforethought," which refers to the defendant's intentions, decisions, and planning related to the homicide. Malice may be shown through deliberate planning or participation in reckless, dangerous activity. When an individual commits a homicide without malice, the state might charge the defendant with manslaughter instead of murder. The difference between murder and voluntary manslaughter often focuses on the defendant's state of mind at the time of homicide.
California state laws define three types of manslaughter: voluntary, involuntary, and vehicular. For a voluntary manslaughter charge, the prosecutor must show that the defendant committed homicide during a sudden quarrel or while in the heat of passion. The events and circumstances surrounding the homicide -- the quarrel or provocation -- establish a lack of malice that would otherwise result in a murder charge. The prosecutor still must show that the defendant had the intent to inflict severe bodily injury or death on the victim in order to prove voluntary manslaughter.
Acts that qualify as provocation depend on the circumstances surrounding the homicide. Some common acts of provocation include:
- Mutual combat between the defendant and victim;
- Murder of a family member; or
- Adultery committed by the defendant's spouse.
If a period of time has passed between the act of provocation and the homicide, California laws provide the prosecutor with the basis for a murder charge as murder can be found where the defendant had a sufficient "cooling period." If the defendant committed the homicide after the cooling period, the prosecutor may be able to show that the defendant had enough time to premeditate or plan the killing.
