SPOKANE, Wash. (AP) — Court documents indicate the estranged wife of a decorated Iraq war veteran arrested in a triple killing says her husband suffered from post- traumatic stress and was becoming increasingly delusional.

Amanda Murry says in the documents released Monday that 30-year-old suspect Roy H. Murry blamed her family for the couple's marital problems.

She says Roy Murry of Lewiston, Idaho, was the only person she suspected of having reason to harm the three people, whose bodies were found last week on rural property near Spokane after a fire was reported.

The three victims were Amanda Murry's mother, brother and stepfather.
