In the first part of the season finale, Billy and Paul talk to a woman who was friends with Yvonne Weber and Maureen Sterling--victims from the Santa Rosa Hitchhiker Murders. She was offered by them to smoke pot with a mystery man. She saw the man. Was never questioned by police and never told her story—-until now. Also there will be updates on Alissa Turney's case, the I-5 Strangler, and theories on the unsolved murders of Abby and Libby from Delphi, Indiana.
