Kenneth Mains points to a small blood stain on the pants which he believes indicates that the killer may have cut himself during the attack on Cheri Jo Bates. Further testing would be necessary to determine if the bloodstain might contain DNA evidence which could identify the killer.

Episode #3 of The Hunt for the Zodiac Killer examines Larry Kane’s possible connections to the 1970 disappearance of Donna Lass in Lake Tahoe, Nevada. In March 1971, a suspected Zodiac message referred to Lake Tahoe and “victim 12,” feeling speculation that the Zodiac may have killed Lass. Sal LaBarbera and Kenneth Mains meet with police to learn more about the Lass case, and they also visit retired Vallejo police detective Ed Rust to discuss Kane as a possible Zodiac suspect. LaBarbera and Mains travel to Lake Tahoe and attempt to find Donna Lass’s gravesite using the clues from the suspected “Zodiac” postcard.
