LINDEN, CA - A spokesman for the San Joaquin County Sheriff's Department says a forensic dentist has tentatively identified human bones recovered from a Calaveras County site last week as those of Chevy Wheeler.

Wheeler, whose body was never found until now, was last seen in October 1985 when she skipped school and took off with Wesley Shermantine. Shermantine is on San Quentin's Death row, sentenced to death for Wheeler's murder and three others.

Deputy Les Garcia announced the Wheeler identification in Linden where searchers are back excavating an abandoned well in search of more human remains believed to be victims of the notorious "Speed Freak Killers."

Garcia said searchersunearthed 700 more bone fragments Tuesday. That is in addition tomore than 300 bone fragments found at the site off E. Flood Road and Escalon-Belotta over the weekend.

The Linden bones and those believed to be Wheeler and Cyndi Vanderheiden, another Shermantine and Loren Herzog victim, will be analyzed by the California Department of Justice for positive identification.

Shermantine led authorities there after a bounty hunter offered him money for information about victims of his killing spree in the 1980s and 1990s. Investigators believe Shermantine and childhood friend Loren Herzog may have killed as many as 20 people.

Sheriff's officials set up a hotline for families that believe a loved one may have been a victim. Officials say they've received more than two dozen calls. The toll-free hotline is (855) 222-1599. Local callers can call (209) 468-5087 or email your name, phone number, the name of the missing person and case number to
