"This is a case of a detective who was super passionate." The 73-year-old Alcala, who appeared on the "Dating Game" during his killing spree, has been incarcerated for nearly four decades.
Alcala was convicted for the women’s murders in 2010 and sentenced to death.
Following his 2010 conviction, the release states, Huntington Beach Police Department Robbery-Homicide Unit released to the public a series of photos Alcala had in his possession in 1979 with the hopes of identifying other potential victims.
The serial killer allegedly met and killed Thornton while on a road trip and buried her on a ranch, according to the Register.
The system assists law enforcement agencies to identify missing people through various means, including comparison of DNA samples from unidentified and missing people and relatives of individuals who can submit their own samples for analysis.
‘Dating Game Killer’ admits to two more murders Authorities give the credit for the new charge to the Huntington Beach Police Department in California.
Six years ago the department released approximately 200 photographs taken by Alcala, hoping people who knew other possible victims would see them.
Earlier this year, as a California jury convicted serial killer Rodney Alcala of five murders in that state, investigators across the country considered whether he also might be a suspect in unsolved killings elsewhere.
Some even suggested that Alcala might be the most prolific serial killer in this country's history.
