I have a question. Where did these come from?
Checked baggage.
From his luggage. Legal to transport there along with ammo in a package where the rounds do not touch.
(assuming you aren’t on a no fly list for being a moslem nutball who walked into an FBI office and saying you are being coerced into fighting for ISiS, and the Army has also been investigating you too....of course if that happened, you’d never be allowed to fly)
he went through three magazines

One can transport a firearm and ammo on a plane if it is checked in locked case separate from checked ammo in locked case. Mags were probably in with the firearm. Got his luggage... went into bathroom.... loaded up mags... went out and started shooting.
