Negligent homicide is the killing of another person through gross negligence or without malice. It often includes death that is the result of the negligent operation of a motor vehicle, which includes the operation of a boat or snowmobile. It is characterized as a death caused by death by conduct that grossly deviated from ordinary care. Negligent homicide may be charged as a lesser-included offense of manslaughter. It is also sometimes referred to as "involuntary manslaughter". State laws vary, so local law should be consulted for specific requirements.
