Details of Disappearance
Vanderheiden disappeared from Clements, California on November 14, 1998. In 1999, Loren Joseph Herzog and Wesley Howard Shermantine Jr. were charged together with her murder as well as other deaths.
They were convicted in 2001; Shermantine was sentenced to death and Herzog to 78 years in prison. However, Herzog's convictions were later overturned and he pleaded guilty to one count of manslaughter and being an accessory to a felony and was sentenced to 14 years, with credit for time served.
Herzog was paroled in 2010. In early 2012, he committed suicide. In the wake of his death, Shermantine offered to lead authorities to the bodies of Wheeler and Vanderheiden, and other victims, in exchange for a cash payment. He claims he killed no one and only helped dispose of the victims after Herzog murdered them.
In February 2012, authorities found the skeletal remains of Chevelle Wheeler on Shermantine's former property in San Andreas, California. Vanderheiden's skull was found in a nearby ravine. Investigators also located 300 human bones and some personal items in an abandoned well in Linden, California. Among the victims in the well were Joann Hobson and Kimberly Billy.
