Nearly four years later, Boyle’s widow, Pauline, has not been told definitively by the Defense Department how he died, which she believes is a result of fratricide resulting in insurance fraud facilitated by the DOD. Several online obituaries do not state the cause of his death. On June 21, 2012, The Chicago Tribune reported that Boyle “apparently died from gunfire.” “I have three death certificates that have three causes of death,” Boyle’s wife Pauline told The Post & Email in a recent interview.
