A former California police officer has been identified as the so-called Golden State Killer believed to have committed 12 killings and at least 50 rapes across California in the 1970s and 1980s, authorities said Wednesday.
Joseph James DeAngelo, 72, was arrested after investigators matched a discarded DNA sample from his home to evidence collected at some of the crimes, according to law enforcement officials at a news conference outside the crime lab where the key break in the case was uncovered.
"We all knew that we were looking for a needle in a haystack," Sacramento District Attorney Anne Marie Schubert said.
"It is fitting that today is National DNA Day. We found the needle in the haystack and it was right here in Sacramento."
DeAngelo was arrested without incident this week in connection with a crime spree that spanned a decade and at least 10 counties throughout California, officials said. His name emerged in connection with the crimes last week.
"When he came out of his residence, we had a team in place that was able to take him into custody. He was very surprised by that," Sacramento County Sheriff Scott Jones said.
DeAngelo, who faces capital murder charges, is being held without bail in Sacramento.
"All too often we forget to talk about the victims and today we at least brought the first step towards closure for those victims of these horrendous crimes," Jones said.
The suspect is a former Auburn, California, police officer who was fired in 1979 for shoplifting a can of dog repellent and a hammer from a drugstore, according to Jones. He worked as a police officer in Exeter and Auburn between 1973 and 1979.
"Very possibly he was committing these crimes during the time he was employed as a peace officer and obviously we'll be looking into weather it was actually on the job," Jone said.
Exeter Police Chief John Hall said, "It is absolutely shocking that someone can commit such heinous crimes, and finding out someone in a position of trust could betray that is absolutely unbelievable."
The Auburn Police Department said it will "do everything within its power to support this investigation and any prosecution that follows."
"We will pull out all the stops for our Sacramento-area law enforcement partners in this horrific and historic case."
From 1976 to 1986, DeAngelo's alleged crimes sowed fear across the state, where the suspect was also known as the "East Area Rapist" and "the Original Night Stalker."
Kevin Tapia, who has lived near Deangelo for 20 years, said the suspect was often heard yelling in his home but, in recent years, had become a recluse.
"He's not like an overly creepy person, but he definitely, you know, kept to himself and kind of was ... a little different," Tapia told HLN. "It was definitely some concern."
Jane Carson-Sandler told HLN on Wednesday that she used to live in Citrus Heights -- where DeAngelo was arrested and resided -- when a man broke into her home and raped her while she and her 3-year-old son were tied.
"When I think back about all of the lives that he destroyed and all of the folks that he has affected over all of these years, I can't help to get angry," she said. "I want to punch him."
Carson-Sandler became the first recorded rape victim on June 18, 1976. In an HLN documentary on the case, she said she was dozing in bed with her son after her husband left for work. Then, she was abruptly awoken.
A masked man stood in the bedroom doorway, holding a large butcher knife and shining a flashlight at her face.
He bound her and her son with shoelaces and blindfolded and gagged them with torn sheets. After moving her son off the bed, he unbound Jane's ankles.
"And then I knew what he was there for," she said in the HLN documentary, in which she didn't share her last name.
That first rape sparked the hunt for the man who authorities say went on to commit rapes and killings in California over the next decade.
It's been more than 40 years since his first recorded attacks, which began in and around Sacramento in Northern California. No suspects were caught or even identified in the case. Police only had minor details about his looks, along with a sketch from an almost-victim.
When the Sacramento-area rapes were first being reported, it was always by women who were alone or with their children. But by 1977, a year after Jane's attack, the list of victims had expanded to couples in their homes.
Police believe the East Area Rapist killed Brian and Katie Maggiore after the couple -- who were walking their dog at the time -- spotted him before he broke into a home in Rancho Cordova, California, just outside Sacramento, in February 1978. Those were his first known homicides.
"We thought he would never stop, but then two months after the Maggiore homicides, the East Area Rapist left our jurisdiction. It was like he disappeared in thin air," said Carol Daly, a retired detective from the Sacramento County Sheriff's Department.
That's when a serial attacker began terrorizing Santa Barbara County, California -- more than 300 miles south of Sacramento. Police didn't realize it at the time, but the attacker's crimes fit the same pattern as Sacramento's East Area Rapist. He attacked women and couples across Southern California from December 1979 to May 1986, and became known there as the Original Night Stalker.
"These cases are some of the most horrific I've had to investigate," said Erika Hutchcraft, an investigator for the Orange County District Attorney's Office. "They're not a one-time, you know, crime of passion, but these are almost passionless crimes. Very cold, very violent."
Even with such distance between Sacramento and Southern California, detectives in the north who heard about the Original Night Stalker believed he was the same perpetrator as the East Area Rapist.
"Over the years, we heard of homicides down in Southern California, and we thought it was the East Area Rapist," said Larry Crompton, retired detective for Contra Costa County Sheriff's Department. "But he would not leave fingerprints, so we could not prove, other than his M.O., that he was the same person. We did not know anything about DNA."
Once DNA tests were available to investigators, they were able to confirm the same man committed three of the attacks that had previously been blamed on the so-called East Area Rapist, according to Paul Holes, who investigated the case for the Contra Costa County District Attorney's Office.
"That's when I reached out to Orange County" in Southern California, he says, "just to see, you know, if the East Area Rapist DNA was a match with the Original Night Stalker."
In 2001, DNA evidence determined the East Area Rapist was the same offender as the Original Night Stalker.
In 2016 -- 40 years after his first attack -- the FBI offered a $50,000 reward for any information that could lead to his arrest and conviction.
"The sheriff's department never gave up on this investigation," Detective Paul Belli of the Sacramento County Sheriff's Department said at the time. "This person ruined a great number of lives, and he should be held accountable."
