Donald James Denninger, 25, of Largo, Florida, was last seen on October 29, 1990. He was living at a residence on 125th Avenue North with his girlfriend, who was the last person to see him. Denninger had been transient in the period before he disappeared and was reported to be struggling with depression and suicidal thoughts.

Out-of-state family members filed the missing person report after police could not locate him while following up on a pending court case. He was wearing a white t-shirt and blue jeans when last seen. The Pinellas County Sheriff’s Office classifies the case as endangered missing and the investigation remains active with few significant leads.
