Murder and nonnegligent manslaughter
As the U.S. Department of Justice, Federal Bureau of Investigation defines it, in the words of its Crime in the United States, 2019: offense definitions.
Official definition
The FBI’s Uniform Crime Reporting (UCR) Program defines murder and nonnegligent manslaughter as the willful (nonnegligent) killing of one human being by another.
The classification of this offense is based solely on police investigation as opposed to the determination of a court, medical examiner, coroner, jury, or other judicial body. The UCR Program does not include the following situations in this offense classification: deaths caused by negligence, suicide, or accident; justifiable homicides; and attempts to murder or assaults to murder, which are classified as aggravated assaults.
