On the evening of January 22, 1985, a husband and wife were discovered deceased inside the Bibb City gas station where the wife was employed. The victims were identified as 41-year-old Danny Williams and his 29-year-old wife, Cheryl. Danny had gone to the Premium Oil Service Station on River Road to help his wife after their four young sons were put to bed for the night. Later that evening, both were found lying face down on the floor of the station, each having been shot twice in the head. Forensic evidence suggested they were on the floor when the fatal shots were fired.
An investigation into the double homicide revealed that the motive was robbery. Approximately $482.79 had been stolen from the service station, along with a knife valued at $35 that belonged to Danny Williams. The investigation led law enforcement to two brothers, David Loomus Cargill and Thomas Philip Cargill. The brothers were seen in a stolen pickup truck near the service station on the night of the murders.
Following their arrests, David Cargill confessed to shooting both Danny and Cheryl Williams. Both brothers were convicted for their roles in the robbery and murders. Thomas Cargill received a life sentence for his involvement. David Loomus Cargill was convicted on two counts of murder and two counts of armed robbery. In July 1985, a Muscogee County jury sentenced him to death for the murders. After years of appeals, David Cargill was executed for the execution-style killings of Danny and Cheryl Williams.
