Following the horrific double-murder-suicide of Josh Powell and his two young sons on Sunday, police have called Josh’s father, Steven Powell, a person of interest in the 2009 disappearance of Josh’s wife Susan.
Police are not calling the elder Powell a suspect at this time, but believe he may know something about what happened to his daughter-in-law, according to Utah’s KSL.com.
“They lived together in the house,” West Valley City, Utah, police chief Buzz Nielsen tells KSL. “There are things he should want to talk to us [about], we hope.”
