Professor Charged in Brother's 1986 Slaying

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. 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. She had told police 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. (More Amy Bishop stories.)
