The nephew of Montana Sen. Jon Tester was brutally killed with his 8-year-old daughter in the next room, according to local reports.

Robert Tester was found dead in his Washington state home Tuesday morning, his body “in a large pool of blood” on the living room floor, according to authorities. His daughter had alerted law enforcement, saying a man entered their home while she was in bed with her father and said he was going to kill her dad.
