Loosely based on the serial killer photographer, Rodney Alcala?

Rodney James Alcala (born Rodrigo Jacques Alcala Buquor; August 23, 1943) is a convicted rapist and serial killer. He was sentenced to death in California in 2010 for five murders committed in that state between 1977 and 1979. In 2013 he received an additional sentence of 25 years to life after pleading guilty to two homicides in New York in 1971 and 1977. His true victim count remains unknown, and could be much higher.

One police detective called Alcala "a killing machine" and others have compared him with Ted Bundy. A homicide investigator familiar with the evidence speculates that he could have murdered as many as 50 women, while other estimates have run as high as 130. Prosecutors say that Alcala "toyed" with his victims, strangling them until they lost consciousness, then waiting until they revived, sometimes repeating this process several times before finally killing them. Police discovered a collection of more than 1,000 photographs taken by Alcala, mostly of women and teenaged boys, most of them in sexually explicit poses. They speculate that some of his photographic subjects could be additional victims.

He is sometimes labeled the "Dating Game Killer" because of his 1978 appearance on the television show The Dating Game in the midst of his murder spree

Despite the difficulty in making his convictions stick, there was never much doubt that Alcala was a prolific killer. In the three trials between 1980 and 2010, he was proven to have murdered seven young women, and detectives maintain that tally is incomplete. Playing out this theory, Huntington Beach Police Department (HBPD) publicly released Alcala's photos at the end the last trial, hoping some of the hundreds of women could be identified, or confirmed missing.
