LOS ANGELES (AP) - Airports around the nation have observed a moment of silence to honor the TSA officer killed by a gunman at Los Angeles International Airport a week ago.
    
With heads bowed and hands folded, passengers and Transportation Security Administration officers alike stopped Friday at LAX as "Taps" was played to remember Gerardo Hernandez. Operations were halted at hundreds of U.S. airports at 9:20 a.m. PST - the same time Hernandez was shot and killed last week.
    
The 39-year-old father of two was the first TSA officer killed in the line of duty. A public memorial service for Hernandez will be held Tuesday morning at the Los Angeles Memorial Sports Arena.
    
Authorities say the alleged gunman, Paul Ciancia (see-AHN'-see-uh), targeted TSA officers. Two other TSA officers and a bystander were wounded before police shot Ciancia, who remains hospitalized
