@abcnews: Travis Decker, the father accused of murdering his three young daughters near a Washington campground, lacked mental health resources and struggled with post-traumatic stress disorder, his ex-wife's attorney told ABC News. The three girls were killed after they left home for a "planned visitation" with Decker on May 30, officials said. At approximately 3 p.m. on Monday, officials located Decker's vehicle unoccupied near a campground and the bodies of the three girls, but "Decker was not located," police said. As of Thursday, Decker may be traveling along the famed Pacific Crest Trail, officials said.
