Michael Del Thomas was a veteran Aurora police officer and U.S. Air Force veteran who had served 24 years. On September 20, 2006, while driving his personal car between training sessions, he was stopped at the intersection of Peoria Street and East Montview Boulevard when a gunman opened fire. The attack was described as unprovoked and proved fatal.

Bystanders and nearby officers subdued the shooter. The man taken into custody was identified as Brian Washington, who was already wanted in Denver for a separate unprovoked shooting the week before. An Adams County jury later convicted Washington of second-degree murder in Agent Thomas’s death, and on April 6, 2009, a judge sentenced him to 80 years in prison.

In August 2025, copies of police reports and other investigation records were found in the crawl space of a retired Aurora detective who had worked the case. Those documents are under review as part of an ongoing appellate motion by Washington seeking to have his conviction and sentence vacated. Did anyone who knew Agent Thomas or who was in that area on September 20, 2006, have information to share?
