Handwritten letters and crude maps might not be needed anymore to discover the remains of the victims of the infamous “speed freak killers.”Last week California lawmakers approved a bill, introduced by Patterson Assemblywoman Cathleen Galgiani, that gives the California Department of Corrections and Rehabilitation more freedom in transporting convicted killers for the purpose of showing investigators and recovery teams where they may have buried their victims. Galgiani – whose 19-year-old cousin Dena McHan disappeared in 1981 – was initially unsuccessful back in January when she attempted to bring all of the moving pieces required for a recovery effort of the victims of Wesley Shermantine and Loren Herzog together. Because Shermantine was on Death Row at San Quentin and Herzog had just been released from High Desert State Prison in Susanville, prosecutors were concerned that being a part of the excavation could affect a future case if Herzog were to be brought up on charges for any additional murders.
