Roy H. Murry either planned and carried out a “swift attack” in May 2015, when he shot three members of his estranged wife’s family and then waited in vain to ambush her before setting fire to the victims’ Colbert home; or Murry, a 31-year-old Republican who was once considered to fill an open state Senate seat, is the victim of Spokane County sheriff’s detectives who immediately focused on the disabled Iraq War vet and pulled out every stop to convince prosecutors he’s a killer. “Mr. Murry has no history of violence,” Public Defender Tom Krzyminski wrote earlier this year in court records. “To date, the physical evidence against Mr. Murry is either nonexistent or a stretch of the limits of imagination.”
