PORTLAND, Oregon (AP) — A U.S. judge on Tuesday sentenced a woman to life in prison for her role in a Pacific Northwest killing spree that authorities say was part of a white supremacist scheme.

Holly Grigsby apologized to friends and relatives of the victims for her actions, but not for her views. Grigsby said she realized any explanation for her behavior, such as her drug addiction, would come across as an excuse.

Grigsby, 27, and her boyfriend, David “Joey” Pedersen, were arrested in 2011 after the deaths of Pedersen’s father and stepmother, along with an Oregon teenager and a California man.

Grigsby pleaded guilty in March to racketeering charges connected to the four killings. The plea agreement called for a life sentence with no chance for release.

Joey Pedersen will be sentenced to life in prison at an Aug. 4 hearing in federal court. He has pleaded guilty to two counts of carjacking resulting in death.

Grigsby expressed no regret for white supremacist beliefs, only the effect her crimes would have on their public perception.

“My actions have further damaged the reputation of a movement misunderstood,” she said. “I deeply regret this.”

Pedersen is the founder of a white supremacist prison gang, and he told Grigsby about his desire to start a revolution with a killing rampage targeting Jewish leaders.

It started on Sept. 26, 2011, when Joey Pedersen shot his father, Red Pedersen, in the back of a head while the elder Pedersen was driving, authorities said. Joey Pedersen and Grigsby returned to the house. Dee Dee Pedersen was bound with duct tape, cut in the neck and left to bleed to death.

The couple then drove Red Pedersen’s vehicle south into Oregon, where they shot and killed 19-year-old Myers and stole his car, authorities said. They shot Myers, who was Christian, because his name sounded Jewish, according to court documents.

Pedersen and Grigsby then headed to California, where Clark, a 53-year-old black man, was shot to death.

Grigsby and Pedersen were arrested Oct. 5, 2011, in California, when a police officer spotted them in Myers’ car. Grigsby told officers they were on their way to Sacramento to “kill more Jews,'” court documents said.

Prosecutors said Grigsby has been a white supremacist since her early teens and did not fall under Pedersen’s spell.
