The bodies were found inside the trailer where the fire began, and the flames had spread to another trailer and a vehicle before being contained by emergency crews. Identities haven't been confirmed, though police are searching for four family members who lived there but haven't been seen since, including Valerie Kambeitz, 34, Lilly Kambeitz, 9, and Emma Kambeitz, 6, and Jayden Kambeitz, 5, police said.
Smith said detectives are talking to people associated with the missing family and investigating possible suspects or people of interest in the case. "Obviously we can't rule out a criminal origin, or rule in anything yet," he said.
A man inside the second trailer by himself was able to escape through a window unharmed. Authorities are obtaining a search warrant and have called in outside resources, including investigators with the federal Bureau of Alcohol, Tobacco, Firearms and Explosives and the Washington State Patrol.
