indeed, it seems quite complex. just kill the girlfriend and the lover, ditch the gun, make your way back to Dulles for the next flight home to china.
I think the girlfriend story is crap.
Bomb threats, loaded with ammo, chains on the doors, indiscriminate shooting with intent to kill large numbers of innocents.
Premeditation...this story hasn’t begun to unfold yet. There’s much information that still needs to be sorted.
