Hillside Stranglers
In America in the 1970's another serial killer was on the loose, preying on young and vulnerable women, whose bodies were found in the hills surrounding Los Angeles. They had been raped and strangled. Nicknamed "The Hillside Strangler", the murderer killed 12 young women over 4 months. Finally the police were led to Kenneth Bianchi, a security guard, who quickly implicated his cousin, Angelo Buono.
Working together these men had enjoyed their reign of terror, but after the longest trial in American legal history Bianchi and Buono were finally behind bars, sentenced to life imprisonment.
