DeAngelo remains in jail in Sacramento, where he is already facing multiple murder charges.
The case of the Golden State Killer, linked to at least 50 rapes and 12 murders between 1976 and 1986, had gone cold - although investigators believed they had a reliable sequence of the perpetrator's DNA.
A meeting was held Friday morning in Santa Barbara regarding the trial of the suspected Golden State Killer with ties to crimes that have happened in Santa Barbara County. Each murder charge comes with special circumstances and carries a maximum sentence of life in prison without the possibility of parole or the death sentence, Dudley said. He was then a police officer in Auburn in Northern California from 1976 to 1979 until he was sacked, officials said.
DeAngelo has also been charged with killing Robert Offerman, an orthopedic surgeon and Alexandria Manning, a psychologist, in their condominium in December 1979.

DeAngelo allegedly went on a decades-long crime spree involving murder, assault, and almost 50 burglary and rape charges from crimes committed between 1976 and 1986.
"Violent cold cases never grow cold for victims or their loved ones", Dudley told reporters.
Investigators said the Golden State Killer found Offerman and Manning in bed before tying them both up and shooting them. "In fact, a lot of them spend their lives feverishly seeking answers and desperately hoping for justice".
After the killer eluded law enforcement officials for decades, DeAngelo was arrested last month with the help of DNA evidence and online genealogy websites.
