Police in Washington state reportedly arrested a Port Angeles man Saturday in connection with a fatal trailer-park fire after multiple bodies were found at the scene.

Matthew Wetherington, 34, lived in the trailer that caught fire early Saturday morning, according to KIRO-TV. He was arrested on suspicion of arson and murder.
