In the final years of GSK's known (and we stress KNOWN) string of vandalism, rapes and murders - from 1980 to 1986 - the killings were less frequent but far more brutal as he transitioned from Central to Southern California.  In this, the third and final installment on the history of the Golden State Killer, Melissa examines not only the brutal, last known murders in his spree - she also divulges some recently-uncovered facts about where the killer may have been living and how he had access to the victims.  Plus - Melissa discusses what might have been GSK's first murder victim way back in 1975 - and how recently-revealed facts tie the man then known only as the Visalia Ransacker to the man who eventually became The Golden State Killer.
