Armed with rakes and an excavator, FBI agents on Tuesday conducted a site survey of farmland near Linden in connection with the "Speed Freak Killers" investigation, authorities said.
Tuesday’s site survey came months after a more intense search uncovered the remains of victims of the killers -- Wesley Shermantine and Lauren Herzog -- before being discontinued.
Shermantine has been convicted of four murders and sentenced to death. Herzog was convicted of three murders and sentenced to 77 years to life in prison, though that was later reduced to 14 years. An appeals court tossed his first-degree murder convictions after ruling his confession was illegally obtained.
Herzog was paroled in 2010 to a trailer outside the High Desert State Prison in Susanville. He committed suicide outside that trailer last month after Sacramento bounty hunter Leonard Padilla told him Shermantine was disclosing the location of the well along with two other locations.
Shermantine’s information led investigators to two sets of remains in Calaveras County. Those remains were identified as belonging to 25-year-old Cyndi Vanderheiden and 16-year-old Chevelle "Chevy" Wheeler.
In February, San Joaquin sheriff's investigators dug up a well and found three sets of remains, two sets identified as missing teens Joann Hobson and Kimberly Billy.
Shermantine, who is on San Quentin’s death row, has told authorities he would aid them further if he was allowed to leave prison under guard and act as a guide.
San Quentin officials said Tuesday that Shermantine was on death row and had not been allowed to leave the facility.
