Three faculty members at the University of Alabama in Huntsville were shot to death, and three other people were seriously wounded at a biology faculty meeting on Friday afternoon, university officials said.

The Associated Press reported that a biology professor, identified as Amy Bishop, was charged with murder.

According to a faculty member, the professor had applied for tenure, been turned down, and appealed the decision. She learned on Friday that she had been denied once again.

The Huntsville Times identified Dr. Bishop as a Harvard-educated neuroscientist. According to a 2006 profile in the newspaper, Dr. Bishop invented a portable cell growth incubator with her husband, Jim Anderson. Police officials said that Mr. Anderson was being detained, but they did not call him a suspect.
