A biology professor charged with killing three of her colleagues at an Alabama university has been indicted in the 1986 shooting death of her brother in Massachusetts, prosecutors announced Wednesday.
Authorities had originally ruled that the shooting of Amy Bishop's brother was an accident, but they reopened the case after Bishop was charged in February with gunning down six of her colleagues at the University of Alabama-Huntsville, killing three.
Bishop, 45, is charged with first-degree murder in the death of her 18-year-old brother, Seth, Norfolk District Attorney William Keating said.
Keating said he did not understand why charges were never brought against Bishop.
"I can't give you any explanations, I can't give you excuses, because there are none," he said. "Jobs weren't done, responsibilities weren't met and justice wasn't served."
Bishop had told police who investigated her brother's death that she accidentally shot him while trying to unload her father's 12-gauge shotgun in the family's Braintree home. Her mother, Judith, the only witness to the shooting, confirmed her daughter's account to police.
But after Bishop was charged in the Alabama shootings, authorities began reinvestigating Seth Bishop's death.
U.S. Rep. William Delahunt, who was then the Norfolk County district attorney, said that Braintree police never told anyone in his office that after Bishop shot her brother, she tried to commandeer a getaway car at gunpoint at a local car dealership, then refused to drop her gun until officers ordered her to do so repeatedly. Those events were described in Braintree police reports but not in a report written by a state police detective assigned to the district attorney's office.
Investigators looking at an old crime scene photo from her brother's shooting discovered a newspaper article about the 1986 killings of actor Patrick Duffy's parents. The clipping, which was in Bishop's bedroom, described how a teenager shot the "Dallas" star's parents with a 12-gauge shotgun and stole a getaway car from an auto dealership.
Keating ordered an inquest, which was held in April. Nineteen witnesses, including Bishop's parents, testified before Quincy District Court Judge Mark Coven during the closed-door inquest. A grand jury heard evidence this month.
Keating said the indictment, brought 24 years after Seth Bishop's death, brought little comfort.
"You're never satisfied when a young boy, a young man, has lost his life," he said. "You're never satisfied when justice isn't served. You're never satisfied, when using your common sense, in all likelihood, three individuals in Alabama that were killed might not have been because the defendant wouldn't have been in that room."
An attorney representing Amy Bishop in the Alabama shootings, Roy Miller, had no immediate comment on the Massachusetts charges. Miller has indicated he is considering an insanity defense for Bishop.
The chief prosecutor in Huntsville, Madison County District Attorney Robert Broussard, didn't immediately return a telephone call seeking comment. He has said an Alabama grand jury would likely consider charges against Bishop in the university shooting by late summer.
