Latest news now, some 4 or 5 hours after the shooting, is that:
* Witnesseses saw a black-clad man with a ski mask and "an AK47" enter the library. Reports of "shots fired" came in at about 8:25 AM.
* Around 9:10 AM police reported that the perp had shot himself on the 6th floor of the library. Police were checking for a possible second shooter.
* No second shooter or victims were found, "All Clear" signal was given about 11:45 AM.
So the current reports are that it ended well - nobody dead or injured but the perp, which is how these things OUGHT to end. Let's hope no bad news (i.e., additional victims) comes along.
(As an aside, I wonder if the perp was on some sort of prescription meds . . . they usually are in these cases.)
