SACRAMENTO, Calif. (AP) - The 737 inmates on California's largest-in-the-nation death row are getting a reprieve from Gov. Gavin Newsom, who plans to sign an executive order Wednesday placing a moratorium on executions.
Newsom also is withdrawing the lethal injection regulations that death penalty opponents already have tied up in courts and shuttering the new execution chamber at San Quentin State Prison that has never been used.
"The intentional killing of another person is wrong and as governor, I will not oversee the execution of any individual," he said in prepared remarks.
Newsom called the death penalty "a failure" that "has discriminated against defendants who are mentally ill, black and brown, or can't afford expensive legal representation." He also said innocent people have been wrongly convicted and sometimes put to death.
California hasn't executed anyone since 2006, when Arnold Schwarzenegger was governor. And though voters in 2016 narrowly approved a ballot measure to speed up the punishment, no condemned inmate faced imminent execution.
Since California's last execution, its death row population has grown to house one of every four condemned inmates in the United States. They include Scott Peterson, whose trial for killing his wife Laci riveted the country, and Richard Davis, who kidnapped 12-year-old Polly Klaas during a slumber party and strangled her.
Newsom "is usurping the express will of California voters and substituting his personal preferences via this hasty and ill-considered moratorium on the death penalty," said Michele Hanisee, president of the Association of Deputy (Los Angeles County) District Attorneys.
That was a similar sentiment expressed by Steve Wagstaffe, San Mateo County's District Attorney, who said that the governor is "trying to override the will of the people."
President Trump also weighed in on Twitter, saying: "Defying voters, the Governor of California will halt all death penalty executions of 737 stone cold killers. Friends and families of the always forgotten VICTIMS are not thrilled, and neither am I!"
While the governor's move is certain to be challenged in court, aides say his power to grant reprieves is written into the state Constitution and that he is not altering any convictions or allowing any condemned inmate a chance at an early release.
A governor needs approval from the state Supreme Court to pardon or commute the sentence of anyone twice convicted of a felony, and the justices last year blocked several clemency requests by former Gov. Jerry Brown that did not involve condemned inmates.
Other governors also have enacted moratoriums. Republican Illinois Gov. George Ryan was the first in 2000 and later was followed by Pennsylvania, Washington and Oregon. Illinois ultimately outlawed executions, as did Washington.
Newsom said the death penalty isn't a deterrent, wastes taxpayer dollars and is flawed because it is "irreversible and irreparable in the event of human error." It's also costly -- California has spent $5 billion since 1978 on its death row, he said.
More than six in 10 condemned California inmates are minorities, which his office cited as proof of racial disparities in who is sentenced to die. Since 1973, five California inmates who were sentenced to death were later exonerated, his office said.
Brown also opposed the death penalty, but his administration moved to restart executions after voters acted in 2016 to allow the use of a single lethal injection and speed up appeals. His administration's regulations are stalled by challenges in both state and federal court, though those lawsuits may be halted now that Newsom is officially withdrawing the regulations.
Brown said he was satisfied with his record number of pardons and commutations, though he never attempted to commute a death sentence. He had focused on sweeping changes to criminal penalties and reducing the prison population.
"I've done what I want to do," Brown said shortly before leaving office, defending his decision not to endorse death penalty repeal efforts in 2012 and 2016. "I've carved out my piece of all this."
Democratic Assemblyman Marc Levine of Greenbrae plans to seek the two-thirds vote the Legislature requires to put another repeal measure on the 2020 ballot. Levine's district includes San Quentin State Prison. A repeal question also was on the ballot in 2016 with the question to speed up executions. It lost by 7 points while the other question was approved by 2 points.
Newsom's aides said it has not yet been decided what will become of the execution chamber, or whether corrections officials have been told to top preparing for executions, for instance by running drills.
Seventy-nine condemned California inmates have died of natural causes since the state reinstated capital punishment in 1978. Another 26 committed suicide. California has executed 13 inmates, while two were executed in other states.
Newsom's office said 25 condemned inmates have exhausted all of their appeals and could have faced execution if the courts approved the state's new lethal injection method.
Notable people on California's death row and their crimes
Here are some notable inmates out of more than 700 people on the nation's largest death row:
-- Rodney James Alcala. Prosecutors said Alcala, now 75, stalked women like prey and took earrings as trophies from some of his victims after they died. He was sentenced to death in 2010 for five murders in California between 1977 and 1979. In 2013, he received an additional 25 years to life after pleading guilty to two homicides in New York. Investigators say his true victim count many never be known.
-- Vincent Brothers. A former high school vice principal, Brothers was convicted of killing his wife, their three young children and his mother-in-law. Prosecutors said he attempted to create an alibi by flying to Columbus, Ohio, with the pretext of visiting his brother. He then drove his rental car to Bakersfield, California, to carry out the killings and returned to Ohio. Now 57, he's been on San Quentin's death row since 2007.
-- Richard Allen Davis. Now 64, Davis has been on death row at San Quentin State Prison since his 1996 conviction in the kidnap-murder of 12-year-old Polly Klaas of Petaluma, California. The case helped gain support for California's "three-strikes law" for repeat offenders.
-- Lonnie Franklin. A serial killer nicknamed the "Grim Sleeper," Franklin was convicted in 2016 for killing nine women and a teenage girl in Los Angeles dating back to the 1980s. He was linked at trial to 14 slayings, including four women he wasn't charged with killing. Police have said Franklin, now 66, may have had as many as 25 victims.
-- Charles Ng. Convicted along with an accomplice, Leonard Lake, of killing 11 people at a cabin in the Sierra Nevada foothills during the 1980s. Lake killed himself in 1985. Ng's prosecution cost California approximately $20 million, at the time the most expensive trial in state history. Now 58, Ng is housed at San Quentin.
--Scott Peterson. After he reported his pregnant wife missing on Christmas Eve 2002, police pursued nearly 10,000 tips, and looked at parolees and convicted sex offenders as possible suspects. Ultimately Scott Peterson was arrested and convicted of the first-degree murder of Laci Peterson and the second-degree murder of their unborn son, Conner, in Modesto, California. Now 46, he's housed at San Quentin.
-- Angelina Rodriguez. Her husband's death was initially ruled undetermined, which meant Angelina Rodriguez was ineligible for a payout on his life insurance. After she pushed for more testing, it was determined that Frank Rodriguez died from antifreeze poisoning. Angelina Rodriguez was arrested for his murder and convicted in 2004. She was also accused -- but never convicted -- of killing her infant daughter in 1993.
