SACRAMENTO, Calif.- Investigators believe that the suspected "Golden State Killer" could be linked to other cold cases.
One of these cases is the unsolved murder of 34-year-old Patricia Neufield in Garden Grove. She lived blocks away from the brother of the suspected killer, Joseph Deangelo.
Neufield was found bludgeoned to death with a bowling pin in 1978. Many pro bono organization are working to solve her case.
"We have reason to believe that a lot of the 'Golden State Killer' cases were based upon opportunity," said Della Donna of Innocense Rights of Orange County. "He would be familiar with a neighborhood, he would start stalking people, and we believe he may have come for Thanksgiving to his brother's house shortly before the holiday and committed this murder."
Another one of the cases is the killing of Joan Anderson from Fountain Valley.
The same group of lawyers brought this case to the attention of the Orange County District Attorney, and they are now investigating it.
Deangelo will be tried on multiple murder counts in Sacramento.
