Between Oct. 18, 1977, and Feb. 17, 1978, bloodthirsty Buono and Bianchi preyed upon unsuspecting females between the ages 12 to 28.
Often posing as cops, the sadistic fiends roamed the streets in their "undercover police car" and forced their victims into the vehicle. They would drive the poor souls to their lair where the women were sexually assaulted and tortured before being strangled to death.
After each murder, the men would thoroughly clean the bodies before posing them in provocative positions on the city's hillsides, thus earning their collective name, The Hillside Strangler.
It was assumed the bloody rampage was the work of one man. But as suddenly as the murder spree began, it all stopped.
No longer able to get along, the killer cousins went their own ways. Bianchi went to Bellingham, Wash., to join his girlfriend and son, and took a job as a security guard.
Before long, he got the urge to kill again. On Jan. 11, 1979, Bianchi lured two Western Washington University co-eds into a house he was hired to protect.
Once again, he raped, tortured and murdered the young women. But Bianchi left behind clues that linked him to the gruesome Los Angeles murders.
