A white supremacist who killed four people in a Pacific Northwest crime speed in 2011 pleaded guilty to federal charges in Portland on Wednesday.

Court-appointed defense attorney Richard Wolf said Wednesday that David "Joey" Pedersen pleaded guilty to two counts of carjacking resulting in death — one for Oregon teenager Cody Myers and the other for Reginald Clark of California.

He is to be sentenced to life in prison at an August hearing.

He previously pleaded guilty in state court to murder in the slaying of his father and stepmother in Everett, Wash.

His girlfriend, Holly Grigsby, pleaded guilty to federal charges last month and will receive a life sentence.
