Bishop, 44, is accused of gunning down three of her colleagues Friday during a University of Alabama-Huntsville faculty meeting in an apparent tenure dispute. Three others were wounded — a rare instance of a woman being accused in a mass shooting.
William Setzer, chairman of chemistry department at UAH, said Bishop was appealing a tenure decision made last year.
"Politics and personalities" always play a role in the tenure process, he said. "In a close department it's more so. If you have any lone wolves or bizarre personalities, it's a problem and I'm thinking that certainly came into play here."
