A brief but provocative commentary over at NewsOne.com raises new questions about the tragic case of Amy Bishop, the troubled biology professor who opened fire on her University of Alabama colleagues last week after being denied tenure.

NewsOne writer RK Byers notes that one detail that has not been heavily publicized in the story is that, out of the three fellow professors Bishop murdered, two of the victims were African American and one was Indian. Bishop also had a history of questionable behavior that could lead one to wonder why she was not already locked up. She “accidentally” killed her 18-year-old brother in 1986 and allegedly sent a pipe bomb to another professional colleague in 1993.
