Walter Burlock was a serial rapist who served time in prison previously, and a suspect in the murder of one of his rape victims. In the early 70s, he raped Joan Arliss, resulting in her being impregnated with a girl she later named Vivian. When he got out, he moved into the home of his cellmate Jason Gambel and blackmailed him into using his basement to rape and kill women. He was killed by his daughter's lover, Sarah.
