Paul Ciancia was so determined to take lives that, after shooting a TSA officer and going up an escalator, he turned back to see the officer move and returned to finish him off, according to surveillance video reviewed by investigators. In a news conference announcing charges against Ciancia, U.S. Attorney Andre Birotte Jr. spelled out a chilling chain of events at LAX that began when Ciancia strode into Terminal 3, pulled a Smith & Wesson .223-caliber assault rifle from his duffel bag and fired repeatedly at point-blank range at a TSA officer. The officer was checking IDs and boarding passes at the base of an escalator leading to the main screening area. After killing that officer, Ciancia fired on at least two other uniformed TSA employees and an airline passenger, who were all wounded. Airport police eventually shot him as panicked passengers cowered in stores and restaurants.
