On March 6, 1987, a local 14-year-old reported being abducted and sexually assaulted. Fairfax County Police made a sketch of the assailant and opened a case that remained open until this year. Now 35 years later, police arrested William Clark for the crime.
DNA analysis is a new technology, the first reported case closed with its help was also in 1987. Old open cases have closed over the years with advances in technology to analyze preserved DNA.
CeCe Moore was Parabon’s lead genealogist involved in the case. Moore begins work after the lab reconciles DNA for genetic genealogy research. DNA analysis supplements Moore’s work but the bulk exists in public records, archives, and media.
