Gov. Jerry Brown said Tuesday he signed a bill to allow a Death Row inmate to help authorities search for the remains of his long-dead victims.
The bill allows the state's corrections secretary to let convicted serial killer Wesley Shermantine help investigators search for more bodies.
Shermantine and a friend were known as the "Speed Freak Killers" for their drug-induced killing spree in the 1980s and 1990s. The other man, Loren Herzog, hanged himself earlier this year after learning Shermantine provided crude maps to lead authorities to the remains of four victims.
