DNA links 1991 killing to Colonial-era family
DNA may help Seattle-area sheriff's deputies find a suspect in a 20-year-old killing after a comparison with genealogy records connected a crime-scene sample to a 17th-century Massachusetts family.
The DNA sample was taken in the death of 16-year-old Sarah Yarborough, who was killed on her high-school campus in Federal Way, Washington, in December 1991. The King County Sheriff's Department has circulated two composite sketches of a possible suspect -- a man in his 20s at the time with shoulder-length blonde or light brown hair -- but had been unable to put a name to the sketch.
In December, though, the department sent the DNA profile to California-based forensic consultant Colleen Fitzpatrick. Fitzpatrick compared the profile to others in genealogy databases and found the closest match was to the family of Robert Fuller, who settled in Salem, Massachusetts, in 1630 and had relatives who came over before him on the Mayflower.
While the descendents of Robert Fuller are likely to number in the thousands after nearly 400 years, geography and physical characteristics can help detectives narrow their search, Fitzpatrick said. In fact, Fitzpatrick said, since the DNA trace follows male descendants, there was "a high degree of probability" that the man police are looking is named Fuller.
