Florida State University police shot and killed a gunman who had opened fire in the crowded university library around midnight. Three people were wounded.
Michael DeLeo, Tallahassee, Fla.'s chief of police, said the gunman appears to have acted alone.
"It will take not only hours but days to put all the pieces together," he said at a news conference this morning. "Obviously, everyone wants to know why, and that's the hard question that we're going to continue to investigate and try to find those answers for everybody."
