Pierce County (Wash.) Sheriff Paul Pastor and Detective Ed Troyer have purchased the burial plots on either side of Josh Powell's boys to prevent him from being buried next to the sons he killed.
Funds for the initiative will come from the anti-crime group Crimestoppers, which Det. Troyer oversees.
Powell was a suspect in Susan Powell's 2009 disappearance from their home in West Valley City, Utah. He attacked his sons with a hatchet and exploded his house in a gas-fueled blaze, killing himself and the two boys on Feb. 5.
