Witnesses say the gunman wore baggy black clothing, entered LAX Terminal 3 and began shooting once reaching the checkpoint. According to LAX Airport Police Chief Patrick Gannon the shooter removed the assault rifle from his bag once inside and began shooting at the checkpoint then moving to the airport screening area shooting his way through.

The mayor said Friday that he would like to, "Thank law enforcement for their excellent and coordinated response to this incident."

"This is a situation in which we are being proactive," the mayor continued. "If you have a flight this afternoon we are asking that you stay away from the airport and check for updates."

Gannon thinks the shooter acted alone.
