Twitpic by Fox Sports columnist Bill Reiter nine minutes ago: "The scene now."
5 p.m. update: The shooter was identified as Paul Anthony Ciancia, a 23-year-old New Jersey native who lives in Los Angeles. He reportedly left a note expressing animosity toward the TSA. Ciancia was wounded by police and is hospitalized. LAX remains in near-chaos as delayed passengers and flights slowly get back to normal.
12:55 p.m. update: Media are now reporting that the suspect is alive in critical condition at a UCLA hospital.
11:27 a.m. update: Law enforcement sources tell NBC and the LA Times that the alleged shooter is dead.
* 11:10 Update:
NBC is reporting a TSA agent was killed in the shooting and another has been wounded. A single suspect is in custody. Flights out of LAX remain grounded and at least Terminals 2 and 3 have been evacuated, with large crowds of passengers outside. News reports say that major streets approaching the airport such as Century and Sepulveda boulevards are closed or severely congested. Avoid the airport if possible while the investigation is sorted out. There has been no announcement yet about when LAX will reopen.
Gunfire has been reported inside the LAX terminal that houses Virgin America and other airlines. There are injured people being reported. A citywide LAPD tactical alert was briefly called then cancelled. Terminal 3 is apparently closed for now.
Fox Sports national columnist Bill Reiter was there and has been tweeting that himself and other passengers fled onto the tarmac.
After the initial burst of gunfire and hiding, people started jumping over one another, jumping off chairs, pushing each other. Chaos & fear— Bill Reiter (@foxsportsreiter) November 1, 2013
First came the gunfire. Then people including me hiding our seats. It felt very Columbine. A new kind of fear, at least for me— Bill Reiter (@foxsportsreiter) November 1, 2013
