On Sunday, for the second day in a row, authorities said they discovered bones, believed to be human, near a well. They also discovered a pair of sandals, a pair of tennis shoes, engraved jewelry and a woman's purse in an area long rumored to hold a mass grave.
A map drawn by Wesley Shermantine, 45, a convicted serial killer who spilled his secrets in exchange for a promise of cash from a bounty hunter, labels two wells on the ranch "Loren's Boneyard."
Shermantine and Loren Herzog were arrested in 1999 for a series of murders known as the "Speed Freak" killings, which may have spanned more than 15 years and claimed an unknown number of victims.
Last week Shermantine's maps led authorities to San Andreas, where they found remains believed to be those of Chevelle "Chevy" Wheeler of Stockton, who disappeared at age 16 in 1985, and of Cindi Vanderheiden, 25, of Clements, who disappeared 14 years ago on a night people had seen her shooting pool with Shermantine and Herzog in neighboring Linden.
