Thomas Shay was one of two men convicted in a 1991 bomb explosion that killed one Boston police officer and maimed another. Prosecutors contended that the bomb was intended for Shay’s father. Shay was a troubled 20-year-old from an unstable background when he underwent a competency evaluation at Bridgewater State Hospital in Massachusetts. Although he found Shay immature and self-centered, psychologist Paul G. Nestor, Ph.D. did not see any signs or symptoms of a severe mental disorder or cognitive impairment that might render him incompetent. Shay pled guilty and served 10 years, after which he has continued to be in and out of trouble with the law. Co-defendant Alfred W. Trenkler, the subject of a personal crusade by a former lawyer named Morrison Bonpasse who has written a book about the case, remains in prison.
