UPDATE: Sheriff Meets With FBI About Search For Victims Of 'Speed Freak Killers'

FRENCH CAMP (CBS13) - The San Joaquin County Sheriff's Office confirmed on Sunday that Sheriff Steve Moore met with the FBI on Friday regarding the search for victims of the "Speed Freak Killers."

According to a department press release, Moore held a meeting with representatives of the FBI, the California Department of Justice, the San Joaquin County District Attorney's Office and sheriff's lead investigators to discuss how best to proceed with future searches for human remains.

Moore has been under pressure to call in the FBI to help with search for victims of Wesley Shermantine and Loren Herzog, who went on a drug-fueled killing spree in the 1980s and '90s before their arrest and conviction on four murder charges.

Investigators have found remains for two of those victims, Chevy Wheeler and Cyndi Vanderheiden, on former Shermantine family property in Calaveras County near San Andreas.

Investigators also removed more than 1,000 human bone fragments from a well near Linden after Shermantine directed them to the area in correspondence from death row at San Quentin State Prison. Herzog, who was out on parole after charges against him were reduced on parole, killed himself last month.

Details of Friday's meeting will not be made available as the open dialog is continuing, the sheriff's office said. An FBI spokesperson told CBS13 on Sunday that the agency had been contacted but is only acting in an advisory role at this time.

Bounty hunter Leonard Padilla, who has been in frequent contact with Shermantine and has offered to pay him for information about victims' locations, has been critical of how Moore has handled the search.

"This thing is not going to be over in the next couple of months," he said. "There's just too many bodies out there."

Padilla told CBS13 that a recall effort against Moore is being explored by others who disagree with how the search has been conducted and his resistance to bring Shermantine out to search sites.

"What they are trying to do is put a meeting together this week and make an effort to for a recall election in November," he said. "Either light a fire under the sheriff or get him out of there and get someone else in who will call the FBI in."

Assemblywoman Cathleen Galgiani, who district includes parts of San Joaquin County, also has sent a letter to the FBI asking the agency to reopen its investigation into the "Speed Freak Killers." The FBI was part of the original investigation when Herzog and Shermantine were arrested in 1999.

"With so much attention on this case now there are so many families reliving the nightmare of a loved one going missing that to prolong this search only puts them through more torture," she said.
