The FBI is focusing on the similarities between six women who vanished—four have turned up dead, two are still missing—in the small town of Chillicothe, Ohio, including the fact that several of them apparently knew each other. While two victims were known friends, relatives of four of the women suggest they ran in the same circles and had likely met, ABC News reports. Yvonne Boggs, mother of missing woman Charlotte Trego, says her daughter knew four of the women who would later vanish or turn up dead, and personally introduced her to three: Shasta Himelrick, Tiffany Sayre, and Tameka Lynch, who vanished, separately, on the same day as Trego. Relatives say at least four of the women had some ties to drugs; two had recently been to rehab.
Though an officer says he can't confirm any specific connections, he tells Reuters, "heroin addiction and prostitution to support the addiction has come up in the investigation." Lieutenant Mike Preston adds that authorities are using "all the manpower that we have available to find out what's going on," but "the investigation has not produced any evidence that one person or persons are responsible." Preston says police have IDed a suspect in the death of Timberly Claytor, who was found in May; he is not suspected in any of the other women's cases. (Read more Ohio stories.)
