Cold Case

Pima County cold case investigations are conducted by our sheriff’s department detectives assigned to the Cold Case Unit. These detectives review the evidence available at the time of the crime, examine and discover new evidence available because of advancing technology, and follow new information provided through telephone and email tip lines.

Submissions will be reviewed to ensure that the applicant is the victim or a family member or lawful representative. Then they will be notified of their inclusion in the registry.
