Robert C. Detwiler, a 36-year-old Caucasian man, was shot and killed in Tucson on August 15, 2020. Officers found him with gunshot injuries in a courtyard at an apartment complex on 8665 East Speedway Boulevard. He was taken to Banner University Medical Center by Tucson Fire Department personnel but died of his wounds.

Homicide detectives say Detwiler was involved in a confrontation with an individual just before the shooting. Witnesses reported seeing the altercation and the suspect running away on foot. Police immediately opened a homicide investigation and announced that no suspects had been identified; they asked the public to contact the Tucson Police Department or the 88-CRIME anonymous tip line with information.

Whoever knew Robert or who saw the confrontation that evening is asked to come forward with details that might help investigators.
