Workers at Lehigh Valley International Airport held a moment of silence Friday afternoon in honor of the TSA officer killed at LAX.

The moment of silence was held at 12:20 p.m., the same time Gerardo Hernandez was shot and killed by Paul Ciancia last week.

Passengers and TSA workers all across the country participated in the event.

Hernandez was the first TSA officer killed in the line of duty. Two other TSA officers and a bystander were wounded during the shooting.
