Dating Game Killer won't come to Wyo.

A serial killer suspected of a 1977 murder in Sweetwater County won’t be extradited to face charges here.

Last week, Sweetwater County Attorney Daniel Erramouspe announced Rodney Alcala won’t be extradited from California due to his health. Alcala is in the hospital wing of Corcoran Penitentiary in Corcoran, Calif., and is unable to leave without medical support.

Alcala is accused of the 1977 murder of 28-year-old Christine Ruth Thornton, of San Antonio, Texas. Thornton’s remains were found northeast of Granger in 1982 by a rancher. While evidence had deteriorated in the years between Thornton’s death and discovery, investigators at the time declared the death a homicide. Thornton’s remains were eventually identified in 2015, two years after Det. Jeff Sheaman of the Sweetwater County Sheriff’s Office picked up the investigation and sent a sample from her remains to the National Missing and Unidentified Persons System.

Alcala was tried and convicted of two murders occurring in 1979 and 1980 and was sentenced to death after his conviction in 1980. His conviction was overturned by the California Supreme Court because jurors were improperly informed of prior sex crimes he committed, but was sentenced to death again after a retrial. That conviction alter would be nullified, removing him from death row. He would be tried a third time, in 2010, for the deaths of four more women who had been matched to Alcala through DNA analysis of evidence collected from the murders occurring between 1977 and 1979. He was found guilty and sentenced to death for a third time.

Alcala, who earned his moniker after an appearance on “The Dating Game,” was also suspected of committing murders in Washington and New York, facing murder charges in New York in 2012. He was again convicted of the charges. Investigators believe Alcala could have been involved in up to 130 murders across the U.S., but admit they do not know the full extent of his crimes.

“The fact that this case will not be proven in court does nothing to dissuade me from knowing that Alcala murdered Ms. Thornton,” Erramouspe said in the press release. “The solving of this cold case, with the random facts, indicates solid investigation and integrity by the Sweetwater County Sheriff’s Office, especially, Det. Jeff Sheaman, along with Sgt. Joe Tomich and Lt. John Grossnickle. It also shows the power of perseverance on behalf of Ms. Thornton’s family, in never giving up the search for their sister,” he said.
