On the night of Wednesday, November 15, 1978, Sergeant Ralph Williams Kimbro, 25, was shot once in the chest and killed while working the overnight shift alone at the Gateway Division Center, a work-release housing facility at 15 Peachtree Street NE in Atlanta. The assailant entered the building, shot Sergeant Kimbro, and fled the scene. No offender is listed and no arrest has been reported.

Kimbro had served 18 months with the Georgia Department of Offender Rehabilitation and previously spent four years with the Tennessee Department of Corrections. He was also a part-time pastor and was survived by his wife.

The motive and identity of the shooter remain unknown. Does anyone have information about Sergeant Kimbro, his patrol that night, or the Gateway Division Center in 1978 that could help this cold case?
