Terry Don Parker, 51, was found dead from gunshot wounds in Sahuarita, Arizona, on Friday, May 17, 2024. The discovery of gun violence in that quiet community prompted a criminal investigation into his death.

Authorities identified 65-year-old Douglas Gauf of Tucson as a suspect. Gauf was initially detained on unrelated drug charges before detectives say they developed evidence linking him to Parker’s killing. He was arrested and charged with first-degree murder and burglary and booked into the Pima County Adult Detention Center; a judge set bond at $500,000.

Court papers describe Parker and Gauf as friends and allege Gauf had been supplying Parker with cocaine. Investigators say they found the presumed murder weapon in Gauf’s possession; the firearm reportedly belonged to Parker and had blood spatter on it. A clear motive has not been made public.

If anyone knew Parker or saw him in Sahuarita around May 17, what information could help investigators further?
