The Speed Freak Killers is the name given to serial killer duo Loren Herzog and Wesley Shermantine together initially convicted of four murders — three jointly — and suspected in the deaths of as many as 72 people in and around San Joaquin County California. They received the speed freak moniker due to their methamphetamine abuse. As of 2013 Shermantine is on death row. Herzog committed suicide in 2012; his conviction had been overturned in 2004 and had been paroled in 2010.
