About these data

The UCR Program's Supplementary Homicide Report (SHR) provides information regarding the age, sex, and race of the murder victim and the offender; the type of weapon used in the murder; the relationship of the victim to the offender; and the circumstance surrounding the incident. Data gleaned from these supplemental reports are provided in this section.

Data Collection

Justifiable homicide - Certain willful killings must be reported as justifiable, or excusable. In the UCR Program, justifiable homicide is defined as and limited to:

  • The killing of a felon by a peace officer in the line of duty.
  • TThe killing of a felon, during the commission of a felony, by a private citizen.
