Walter Mueller was 32 when he left work on North Nevada Avenue on March 8, 1988, saying he felt ill and was going home. He never arrived, and more than a month later his body was found off Rampart Range Road on April 11, 1988. An autopsy determined he died of multiple gunshot wounds, and the case was treated as a homicide.

The El Paso County Sheriff’s Office investigated, but no suspects have been publicly identified and no arrests have been announced. The case grew cold over the years and remains unsolved, leaving family and investigators without answers.

Did anyone in Colorado Springs in March–April 1988 remember seeing Walter, his car, or unusual activity near Rampart Range Road that could help bring new leads?
