Scientists hoping to find the person responsible for the 1991 slaying of 16-year-old Sarah Yarborough of Federal Way say they have found an ancestor of the alleged killer — a very distant relative.

DNA testing has linked Yarborough’s killer with the extended family of Robert Fuller, who arrived in North America in the 1630s, the Sheriff’s office says.

Yarborough, aFederal Way High School student, was last seen alive on the morning ofDec. 14,1991, when she was leaving her house for adance team competition, according to the King County Sheriff’s Office. She was found slain on her school campus.

Witnesses told police that they saw a white man, in his 20s, about 5-feet-10 to 6-feet tall with shoulder length blond hair in the area at the time. The man had a medium build and was wearing a trench coat and dark-colored pants, according to the sheriff’s office.

Suspect DNA was obtained from Yarborough, and the evidence was sent toIdentiFinders International, a California-based forensic genealogy firm. Scientists say thesuspect’s DNA is related toFuller, who arrived in Salem, Mass. in the 1630s. Fuller is related to two Fullers who arrived in America on the Mayflower.

Sheriff’s deputies say that Yarborough’s killer might even have the the last name of Fuller.
