William Clark

William Clark, 59, was arrested on April 18, 2022, for the March 6, 1987 rape of a 14-year-old girl in Fairfax City, Virginia. The suspect had telephoned the girl’s mother claiming to be well-known radio personality Don Geronimo and that she had won a $1000 prize and a trip to Hawaii. He used this ruse to obtain her home address and personal information. He phoned again and told the girl she needed to come to the radio station in person to claim the prize. When she arrived, he kidnapped her and drove her to the woods, where he sexually assaulted and then left her.

Police were telephoned, and a forensic sample of the suspect’s DNA was taken from the victim. The FGG investigation was conducted by Parabon Nanolabs. Police have not disclosed how they made the initial confirmation, only that they obtained a sample of Clark’s DNA.

Clark is facing charges of rape, abduction with intent to defile, and attempted forcible sodomy in Fairfax County General District Court Criminal Division. He is being held without bond.
Police state that they investigated over 70 other suspects in this case who had their DNA samples taken and compared with the crime scene DNA profile. All of them were eliminated.
