Charles Manson has become an icon of evil since his arrest for orchestrating the 1969 murders of seven people by his cult "family." Although sentenced to death, he was reprieved from the death sentence when California ended the death penalty in 1972. Thirty-eight years later, investigators believe they may have discovered additional murders conducted by Manson and his "family."

Following the known 1969 murders, Manson and his "family" hid themselves at the Barker Ranch in Death Valley, California. Recent discoveries at the Barker Ranch show evidence of possible graves and DNA in the soil. Using the very latest technology, investigators are searching underground for human remains.
