KENNEWICK, WA – The Benton County Sheriff’s Office is searching for a 68-year-old man who is wanted for arson and murder after a mobile home fire in Kennewick Monday morning.

Investigators say a neighbor called 911 and raced to make sure dogs in the double-wide managed to escape.

The fire burned unusually hot, firefighters told us, because of the home’s metal exterior.

Once things finally cooled down enough for firefighters to get in safely, they found a body inside the burned home.
