Under existing law, a person commits the crime of murder or manslaughter if the person causes the death of another person under certain circumstances. Murder is a Class A felony and manslaughter is a Class B felony. This bill would require any person who causes the death of another person using a machinegun under certain circumstances to be sentenced to life imprisonment without the possibility of parole if the defendant was 18 years of age or older at the time of the offense and to either life imprisonment without the possibility of parole or life imprisonment if the defendant was under 18 years of age at the time of the offense. Under existing law, a person commits the crime of assault in the first degree or assault in the second degree if the person causes injury to another person under certain circumstances. Assault in the first degree is a Class B felony and assault in the second degree is a Class C felony. This bill would provide that assault in the first degree and assault in the second degree where a machinegun is used is a Class A felony and the person shall be sentenced to life imprisonment. This bill would also define the term machinegun.
