FILE – In this Oct. 21, 2016, file photo, Sharon Scott, left, and Sheila Williams console each other near a sculpture of an unidentified 1985 female murder victim during a forensic conference in Tampa, Fla. They believe the victim could be their missing sister, Brenda Williams. The family of the Florida woman who disappeared decades ago has received some long-awaited news. Tampa Police matched the DNA of two sisters to a jawbone discovered by a schoolboy in 1986. The jawbone was that of Brenda Williams, a young mother of two who went missing in 1978.
