STOCKTON (AP) — Information provided by a California death row inmate who was one of the two notorious “Speed Freak Killers” led to the discovery Friday of a second set of human remains, this time believed to belong to a 16-year-old girl who went missing nearly three decades ago.Specially trained dogs led authorities to a partial human skull and bones buried on a remote Calaveras County property, said Deputy Les Garcia, spokesman for the San Joaquin County Sheriff’s Department, which is leading the search.Garcia said it would take some time for the Department of Justice to make a positive identification. However, the parents of Chevelle “Chevy” Wheeler said authorities notified them that the remains were discovered where death row inmate Wesley Shermantine said they would find their daughter, who disappeared while skipping school in 1985. Shermantine was convicted of her murder, which authorities say was part of a methamphetamine-fueled killing spree committed by him and his childhood friend, Loren Herzog, from the 1980s until their arrests in 1999.“They said they found her wrapped in a blanket,” Paula Wheeler, the girl’s mother, told The Associated Press in a phone interview from the family’s home in Crossville, Tenn.
