(LINDEN, Calif.) -- More than 300 human bones have been found in a Linden, Calif., mine where "Speed Freak" serial killers Wesley Shermantine and Loren Herzog buried victims of their alleged drug-fueled killing spree.
Shermantine, who is on death row, provided a hand-drawn map to San Joaquin sheriff's officers to help them locate the burial ground for as many as 10 or more victims from the spree, which occurred during the 1980s and 1990s.
Herzog, when he was told about Shermantine's cooperation with investigators, killed himself last month.
Monday marked the fourth day of searching and sifting through dirt from the mine, which police excavated in batches and then combed through for evidence. In addition to bones, investigators have found clothing, shoes, jewelry, and other personal effects.
The sheriff's department said it's too early to tell how many different bodies they've found. They say the next step is sending all the tagged items to the Department of Justice for DNA analysis.
