While Wesley Shermantine has drawn maps showing where he says he and the late Loren Herzog dumped dozens of bodies of victims Shermantine maintains Herzog killed, interrogation tapes made by authorities in March 1999 show Herzog claiming it was Shermantine who did all the slaying.

The two boyhood friends graduated from Linden High School in 1984.

Herzog told police that it was just a few months after their graduation that he and Shermantine  fatally shot and robbed their first victim, a stranger on the side of a road.

In an excerpt from the 1999 tapes, a detective asks Herzog if Shermantine would "kill somebody for 45 bucks?"

Hezog replies "He'd killed somebody for less than that, man. He would. He'd kill 'em for nothin'. No matter what. I hope you guys believe me..."

In the tapes, Herzog admits he was at the scene of many other crimes. 
 
At one point, the interrogating detective asks "Has he described any others to you that he has done? You said that he's killed over...20?"

"He told me about Chevy Wheeler," answers Herzog.

16-year-old Chevy Wheeler  cut school in October 1985 to hang out with Shermantine and was never seen again. Her remains were recently uncovered in Calaveras county.  

Her mother Paula Wheeler currently lives in Tennessee. She told KTVU she plans to hold a memorial service for Chevy this weekend.

"Finality, finally," said Paula Wheeler. "We never thought we would be getting  her back." 

The mother of 16-year-old Joann Hobson of Stockton told KTVU her daughter went on a date with Herzog two months before Chevy disappeared. Joann never came home either.

Investigators also questioned Herzog about 24-year-old Robin Armtrout of Stockton, who turned up dead around the same time.

It appears the last victim of the "Speed Freak Killers" spree was 25-year-old Cyndi Vanderheiden of  Clements. She disappeared in November 1998.

Herzog's attorney told KTVU the interrogation led to Shermantine's arrest, ending the killing rampage.

"We're gonna be putting him away," a detective can be heard telling Herzog. "I wanna see his ass on Death Row, honestly.  It's my personal feeling."

"Me too," replies Herzog on the tape. "I just don't wanna be there with him.  You know what I mean?"

Some of the videotapes KTVU received copies of eventually helped Herzog's defense team overturn most of his convictions when a court determined some of the admissions were coerced.

Herzog killed himself last month just hours after learning that Shermantine was going to reveal where the bodies could be found.
