PORTLAND, Ore. (AP) — A woman who claimed ties to white supremacist prison gangs has pleaded guilty to a conspiracy that involved four deaths in three states, guaranteeing herself a life sentence.
Holly Grigsby and David Pedersen were accused in the killings of Pedersen's father and stepmother in Everett, Wash, an Oregon teenager and a California man.
Pedersen previously pleaded guilty in state court to murder in the slayings of his father and stepmother.
Grigsby pleaded guilty in federal court Tuesday to racketeering charges connected to the four killings.
Under the agreement, Grigsby will not be prosecuted in state court in Oregon, Washington or California.
Pedersen is to be tried on federal charges in U.S. District Court in July.
Attorney General Eric Holder decided not to seek the death penalty.
