(CBS/AP) GRAHAM, Wash. - A search in Washington of a recycling center near Graham recovered some papers, books and a map of Utah belonging to Josh Powell and his missing wife.
Powell and his two sons were found dead in his home on Feb. 5. Powell reportedly attacked the boys with a hatchet then set the home on fire.
Volunteers combed through more than 10 tons of paper over the weekend looking for materials Powell dropped off the day before his death.
Searchers found what the Pierce County sheriff's office called a "testament" with Powell's name on it. They also found some paperback books with his wife's name on them and the Utah map.
A Pierce County sheriff's sergeant told KIRO-FM that detectives are analyzing the materials for any value as evidence.
Investigators are still looking for the body of Susan Powell, who disappeared in 2009 in Utah.
