The FBI began to search for more victims of the “Speed Freak Killers.” Loren Herzog and Wesley Shermantine received their nickname due to their use of methamphetamines.
They were initially convicted of four murders, three of which they did together. However, they are suspected of killing as many as 72 people, in and around San Joaquin County, California.
In 2010, Herzog was paroled to a trailer near the High Desert State Prison in Susanville. He committed suicide by hanging himself at the trailer after he found out Shermantine, who is on death row, was planning on telling the authorities three locations, including a well in which the duo buried their victims.
Shermantine only began cooperating with authorities after Sacramento bounty hunter Leonard Padilla promised to pay him approximately $30,000 for giving them the location of bodies.
Authorities recovered bones from the well in 2012, and they have been positively linked to the “Speed Freak Killers.”
“We all remain hopeful that our efforts at this site will ultimately return the remains of victims to their loved ones but know that such is not a certainty,” Herbert Brown, the agent in command of the FBI’s Sacramento office.
