Dating Game Killer

Rodney Alcala, Guillermo Díaz is a convicted serial killer whose crimes span decades and oceans of victims. In 1971, he is arrested after assaulting 8-year-old Rosie Hoffman, Gina Shmukler, but because her parents move to Mexico, she cannot testify at his trial and he is charged only with assault. Despite repeated accusations of abusing girls, Alcala’s calm demeanor and polite, disarming charm help him earn preferential treatment and relatively light sentences, allowing him to continue his crimes for years. The early investigation is led by Detective Jim Hamell, Robert Knepper, with Detective Ryan, Matt Barr, joining as new patterns emerge. The case unfolds with a methodical, troubling tension between a seemingly affable man and the brutal reality of his acts.

In 1978, amid his killing spree, Alcala becomes a public figure of a horrifying paradox when he appears on the television show The Dating Game, a jaw-dropping moment that contrasts with the darkness of his actions. The case gains traction when a park ranger, Greg Parvess, identifies him walking with Tammy Jensen, [Daniah De Villiers](/actor/daniah-de-villiers, a young victim whose body is later found in the same location. The ranger’s eyewitness account, together with the discovery of Tammy Jensen’s earrings in Alcala’s Seattle storage locker, provides police with crucial evidence to pursue charges more vigorously.

Alcala is ultimately sentenced to death, but the conviction is overturned in 1984 due to prosecutorial references that biased the jury. He is retried and reconvicted, receiving another death sentence in 1986. A series of legal changes, including the expansion of DNA collection, helps connect him to additional murders long after the initial trials. In a striking turn, Alcala represents himself at a 2013 trial, answering his own questions from the defense chair and continuing toChallenge the process from within the courtroom.

Rosie Hoffman returns to testify after 42 years, joined by Carol Jensen, Tammy Jensen’s mother, who describes the impact of the disappearances and murders on families and communities. Their testimony helps secure new convictions on multiple counts of abduction and murder, underscoring the enduring reach of Alcala’s crimes. The case also spans other states: in 2012, Alcala pleads guilty to two more murders in New York, and in 2016 he faces charges in connection with a 1977 Wyoming murder, illustrating a decades-long trail of violence that authorities work tirelessly to close.

Throughout the narrative, the tension between Alcala’s public persona and his private violence remains central, revealing how a calculated predator could slip through cracks long enough to commit a vast and deadly reign of terror.
