William Blankenship

William Brian Blankenship was charged on February 11, 2020, with three home invasion rapes that took place in Cincinnati, Ohio between 1999 and 2001. The victims included an adult woman, a 14-year-old girl, and a 10-year-old girl. This youngest girl was kidnapped from a camper in her driveway and taken to a nearby field where she was sexually assaulted.

These cases were linked through DNA profiles obtained from the victims’ sexual assault kits. The FIGG investigation was conducted by The FIGG investigation was conducted by Barbara Rae-Venter and a team that worked on the investigation into the Golden State Killer, including Stephen Kramer, Melissa Parisot, Monica Czajkowski, and Kirk Campbell.

Parabon Nanolabs also worked on this case. Investigators also used Y-STR DNA to narrow down the male lineage to whom the suspect belongs. Investigators were then able to obtain a search warrant for a sample of Blankenship’s DNA to confirm that his profile is consistent with that found at the crime scene.

Authorities in Cincinnati alerted investigators in Campbell County, Kentucky, where Blankenship was a long-time resident. As a result of their investigation, Blankenship was charged for sexual assaults on six further victims. Three of the victims were adults, and two were around twelve years old. Prosecutors have not stated whether they have DNA evidence in these cases.

The final victim, described as being between 12-14 years of age, was known to Blankenship who groomed the child over a period of two years from about 1989 to 1991. He is charged with statutory rape in connection with this victim, who has come forward only recently.

On February 10, 2023, Blankenship pled guilty in Hamilton County to three counts of rape; in exchange, the other charges against him in that jurisdiction were dismissed.
