Donald Robert Laabs was 28 when his promising law enforcement career ended on the evening of December 18, 1975. Newly promoted to detective sergeant with the Manitou Springs Police Department and working as an undercover narcotics agent, he had a record of multiple drug arrests across Colorado.

Witnesses saw Detective Sergeant Laabs leave the police station around 8:00 p.m. and head toward his home in Security, Colorado, using the U.S. 24 Bypass toward Colorado Springs. About two hours after he was last seen, he was found in his police vehicle on the southbound side of Interstate 25 just north of the Arvada Street exit in Colorado Springs, having been shot eight times with a .22 caliber handgun. Investigators reported he had been able to fire his own weapon at his assailants before dying. No motive, arrests, or publicly identified suspects have been reported, and the case remains unsolved.

Did anyone who knew Laabs, his patrol routes, or his undercover work in 1975 have information that could help reopen leads?
