PROPERTY & EVIDENCE

How to Retrieve Your Property

SIU manages all property and evidence for the Sheriff’s Office, including over 25,000 items such as firearms, narcotics, digital devices, and other property. Staff track and maintain these items and work to resolve each one as quickly as possible. Depending on the case, property may be returned to its rightful owner, kept for department use, donated, or safely destroyed in accordance with all applicable laws.

  • Once the eligibility letter is received, you have 30 days to schedule an appointment and pick up the firearm
  • Bring your letter to your appointment — SIU staff will verify your eligibility
