Authorities are poring over papers belonging to Josh Powell that were found at a recycling center over the weekend, along with books and a map of Utah. Volunteers sifted through more than 10 tons of paper to find items that Powell had dropped off the day before blowing himself up along with his two sons, the AP reports. Among the papers is what the sheriff's office calls a "testament" with Powell's name on it, although authorities did not elaborate on what it contains.
Books with the name of Powell's missing wife, Susan, were also found, along with a map of the state where she went missing. "We'll take what we have and analyze it and determine if it has evidentiary value or if it leads us to another location," a sergeant tells KIRO-FM. A bloodstained comforter found last week in Powell's storage unit is also being tested by investigators. On Saturday, more than a thousand people mourned Charlie Powell, 7, and Braden Powell, 5.
