The Dating Game Serial Killer

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,^[2] and is currently under indictment for two additional homicides in New York.^[5] His true victim total remains unknown, and could be much higher.^[6][7][8] Alcala is also notable for exceptional demonstrations of cruelty: prosecutors say he "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.^[9][10]

He is sometimes labeled the "Dating Game Killer" because of his 1978 appearance on the American television show The Dating Game in the very midst of his murder spree.^[11] Police discovered a collection of more than one thousand 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.^[9]
One police detective called him "a killing machine",^[12] and criminalists have compared him to Ted Bundy.^[13]

A homicide investigator familiar with the evidence speculated that Alcala could have murdered as many as 50 women,^[7] while other estimates have run as high as 130.^[14]
