SAN FRANCISCO — Authorities searching with the help of a convicted serial killer found more human remains Saturday — the first bones discovered at an abandoned well on a cattle ranch where a death row inmate claimed 10 or more victims may be buried, authorities said.
The discovery marked the third straight day that remains were found with a map prepared by Wesley Shermantine. He and his childhood friend, Loren Herzog, were called the "Speed Freak Killers" for a methamphetamine-fueled killing spree that had as many as 15 victims.
Two sets of remains had been found Thursday and Friday near property once owned by Shermantine's family about 60 miles south of Sacramento.
The latest remains were found after crews dug slowly through 30 feet of soot and debris at the well near Linden, Calif., said San Joaquin County sheriff's spokesman Deputy Les Garcia.
It was not clear whether they belonged to one or more people, and Garcia said they had not yet been identified.
