Wyoming Division of Criminal Investigation


The 2024 Wyoming Legislative Session, by means of HB0029, legislated the Division of Criminal Investigation to develop and maintain a cold case database.  DCI set out to develop and maintain a database consisting of Wyoming unsolved homicide and sexual assault information to uncover case connections, develop leads, identify suspects, and solve cases bringing closure to victims and their families.  By legislation, a "cold case" means a homicide or felony sexual offense that occurred after January 1, 1972 and remains unsolved for two (2) years or more after being reported to a law enforcement agency.  DCI is pleased to announce the public will be able to view the collected information as permissible by law.  The cold case data viewer is available via the DCI website on the Cold Cases webpage as of July 1, 2024.  Law Enforcement may request access and submission capabilities by email to dci-wycoldcases@wyo.gov .

The Wyoming Division of Criminal Investigation (DCI) was created  in 1973 pursuant to Wyo.Stat. § 9-1-611. DCI is a division of the Wyoming State Attorney General's Office. The history of DCI can be read at this link. DCI is comprised of Criminal Justice Information Services, Operations, and the State Crime Laboratory.  

The mission of DCI is to provide exceptional service to our criminal justice partners and the citizens of Wyoming through leadership, teamwork, and cooperation while exhibiting a positive attitude with Dedication, Courage and Integrity.
