Pierce County Sheriff's Dept. Investigating Josh Powell Murder-Suicide

The Pierce County Sheriff’s department is investigating a murder-suicide connected to a high-profile missing person’s case.

Yesterday Josh Powell killed himself and his two young sons when he set fire to his house near Graham, Washington.

His wife Susan Powell has been missing since 2009. Josh Powell was the only “person of interest” in her disappearance, though he repeatedly denied involvement.

Ed Troyer from the Pierce County sheriff’s department says police hope to have more information today .

"We are going to have the fire marshall’s office and arson detectives at the scene going through the rubble and seeing if we can determine some more details on the fire and what happened at the house," Troyer says. "And we also have the autopsies today. And our detectives are following up on leads, contacting family members. Hopefully by end of day we’ll have some more answers as to what happened."

However, Troyer says he will not have answers about Powell’s motivation.

"We’re not ever going to be able to say why. A lot of people are asking why and that answer died with Josh Powell."

Sunday a social worker brought Powell’s five and seven-year-old sons over for a supervised visit. But Powell let the boys in and locked the caseworker out. She smelled gas and called her supervisor.

Minutes later, the house burst into flames.
All three died. Troyer says the social worker did all she could.

Recently, the boys had allegedly begun to talk about their mother's disappearance.
The older child told his maternal grandparents that his mom was in the trunk of a car driven by his father Josh Powell in December of 2009.
