How to Become a Crime Scene Investigator Forensic Scientist in Cheyenne, Wyoming

Despite advances in forensic technology, detectives are still unable to solve the murder case involving a man stepping out of his car to confront another man on one of Cheyenne’s busiest intersections. Police have bullet casings, witness reports, and video camera footage relating to the incident, but have not secured any convictions in the case which is now over a decade old.

Members of the Cheyenne Police Department’s Major Crime Scene Unit along with evidence technicians are involved in cold cases such as this, plus new cases that come up every day. Forensic evidence that is gathered at crime scenes by these CSI agents is then transferred to the Wyoming Division of Criminal Investigation’s State Crime Laboratory, conveniently located in Cheyenne. Last year a collaborative effort between these two agencies secured evidence for criminal prosecutions in 21 robbery and 21 rape cases that were perpetrated in Cheyenne.
