Well, at least what we know until we go live at 11:35 p.m. Because let’s be honest — the twists are coming fast and furious in the wake of the latest campus shooting. Since leading Friday night’s show with this short segment “Faculty Rampage,” we’ve been puzzled by revelations about Professor Amy Bishop, her past and how the pressure of academia may have caused her to snap. Bishop is accused of killing three of her colleagues and injuring three more inside a biology department faculty meeting at the University of the Alabama Huntsville. A major revelation, that she, then 19, “accidentally” killed her 18-year-old brother in 1986 in the family’s suburban Boston home. This blog Saturday sparked an interesting commentary about the tenure system and whether authorities in Massachusetts somehow screwed up. But wait, there’s more. It turns out this mother of four was investigated but never charged with sending a mail bomb in 1993 to the home of a Harvard Medical School professor with whom she may have butted heads. The crude explosive failed to detonate. Her husband has commented on the case, likely more than his wife’s attorney would care. We learned about Bishop’s trip to a firing range. And now, a possible hero figure, Debra Moriarity, a Huntsville biochemist professor who says, along with other survivors, that she stepped in to confront Bishop and was spared when the gun ran out of bullets. Curiously, Matt Drudge has framed the story in a political light, with a headline on his Web site linking to this Boston Herald report describing, through an unnamed Bishop family source, as a “far-left political extremist” who was “obsessed” with Barack Obama. Not sure the story is there yet. Tonight, a long-form update on the bizarre case from Andrea Canning, who is in Boston, with additional reporting from Clayton Sandell and his team in Alabama. ——————– UPDATE: Embedded below is last night’s segment.
