The homicide unit, which consists of two Sergeants, nine detectives and one analyst, is responsible for the investigation of all homicides in unincorporated Polk County. In addition, they conduct investigations in all unattended natural deaths, accidental deaths, suicides, child and infant deaths, or any death that is deemed suspicious in nature. The homicide unit investigates all officer-involved shootings by sheriff’s office members and other agency shootings at the request of that agency. The Polk County Sheriff’s Office also works death investigations for local police agencies at the request of that agency. All “in-custody’ deaths are thoroughly investigated by the homicide unit whether they occur at a Polk County Sheriff’s Office Detention facility or an individual dies while in the custody of a member of the Sheriff’s Office before arriving at a Sheriff’s Office Detention facility.
