An ex-professor pleaded guilty Tuesday to fatally shooting three colleagues and wounding three others at the University of Alabama in Huntsville, 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
