The Homicide Unit is comprised of six active homicide teams. Each team has one sergeant and four detectives. The Homicide Unit also has one Cold Case Team. They are all supervised by a lieutenant. The Homicide Unit uses murder clearance rates, as defined by the Federal Bureau of Investigation's Uniform Crime Report (UCR), as one of it's measures of success.

Under FSS 782.04 the homicide category includes both criminal and non-criminal offenses such as:

 

  • Murder - the unlawful, willful killing of one human being by another.
  • Manslaughter - the killing of a human being by the act, procurement, or culpable negligence of another. This is a criminal offense.
  • Justifiable homicide - the killing of another human being while resisting another person attempting to murder or commit a felony against said person. Justifiable homicide is a non-criminal offense.
  • Excusable homicide - the killing of another human being by accident or misfortune while doing any lawful act by lawful means with usual ordinary caution and without any unlawful means. Excusable homicide is a non-criminal offense.
The six active homicide teams also handle death investigation cases such as murder, manslaughter, suicide, accidental death (non-traffic related), in-custody death, death of a suspicious or undetermined nature where a doctor will not sign the death certificate, and any incident (except traffic crashes) resulting in life threatening injury. Life threatening injuries caused by traffic crashes are investigated by the Traffic Homicide Unit.
 
The Cold Case Team handles all unsolved homicides for which new information or technology is available, and if the original detective is no longer in the unit, and the crime remains unsolved.
 
The Cold Case Team also investigates officer-involved shooting incidents (when an officer shoots someone or is shot, regardless of the injury extent) and officer-involved custodial incidents with life threatening injury.
