Holly Grigsby apologized today to friends and relatives of the victims. Grigsby said she realized any explanation for her behavior would come across as an excuse.
Grigsby 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.
