BIRMINGHAM, Ala. (AP) An ex-professor pleaded guilty Tuesday to fatally shooting three colleagues and wounding three others during a faculty meeting at the University of Alabama in Huntsville in 2010, court officials said.
Amy Bishop, 47, pleaded guilty to one count of capital murder involving two or more people and three counts of attempted murder. She had earlier pleaded not guilty by reason of insanity
Prosecutors were seeking the death penalty against the Harvard-educated Bishop and it was not immediately clear if they would drop the penalty as part of the plea deal, which is common in such cases. Sentencing will be after arguments are heard at a hearing on Sept. 24 before Madison County Circuit Judge Alan Mann in Huntsville.
Prosecutors say the former biology professor on Feb. 12, 2010, pulled a gun out of her purse and opened fire at the meeting. Her attorneys say she had mental problems.
Bishop of Huntsville also is charged with killing her brother in Massachusetts in 1986. The shooting of 18-year-old Seth Bishop had been ruled an accident after Amy Bishop told police she shot him in the family's Braintree home as she was trying to unload her father's gun.
But the Alabama slayings led to a new investigation and charges.
In the university shooting, police and people who knew Bishop have described her as being angry over the school's refusal to grant her tenure, a decision that effectively would have ended her employment in the biology department at UAH.
The gunfire killed Bishop's boss, biology department chairman Gopi Padila, plus professors Maria Ragland Davis and Adriel Johnson. Professors Joseph Leahy, staff aide Stephanie Monticciolo and assistant professor Luis Cruz-Vera were shot and wounded.
Debra Moriarity was in the faculty meeting at the time of the shooting and is now biology chairman at the school. Prosecutors who met with potential witnesses last Friday said there was a possibility of a plea agreement before the trial began on Sept. 24, she said.
"So I'm not totally surprised by it, but I am surprised it happened this soon," she said.
