LES,
Voluntary manslaughter is intentionally killing another person in the heat of passion and in response to adequate provocation.
Voluntary manslaughter sentencing will vary by case and jurisdiction, but most convictions result in prison time. According to federal sentencing guidelines, the penalty for voluntary manslaughter consists of fines, 10 years or less in prison, or both.
Involuntary manslaughter is negligently causing the death of another person.
Involuntary Manslaughter is a category D felony here in Nevada, which means that it carries with it: A prison sentence of between 1 and 4 years in a Nevada State Prison; and. Possible fines up to $5,000.00.
Penalties for voluntary manslaughter are significantly less severe than penalties for murder, which could potentially result in life in prison. In California, voluntary manslaughter is a felony and could result in the following penalties: Three, six, or eleven years in California state prison. A fine of up to $10,000.
I'm not sure just yet if the manslaughter penalties are the same in each state such as California, Nevada, or Arizona nor even which state would have jurisdiction, but some GetBiggers may be smart enough to clarify.
