James Perry Sinclair was 49 when he was killed in Burlington, Colorado, on January 1, 1976. The death was officially classified as a homicide by the Kit Carson County Sheriff’s Office, though specific details about how he was killed and the early investigative work have not been widely published.

Sinclair, born August 12, 1927, remained the subject of a long, unresolved inquiry and his case was listed among cold cases worked by the Colorado Bureau of Investigation. Authorities later announced an exceptional clearance, stating a suspect had been identified but that the person responsible was deceased, so there was no public trial or conviction. The suspect’s name and the investigative details leading to that conclusion were not released.
