LOS ANGELES (AP) - The 100-foot pylons at Los Angeles International Airport will be lit blue this weekend in honor of a transportation security officer who was killed in a shooting. Authorities say 23-year-old Paul Ciancia strolled into Terminal 3 Friday, pulled a semi-automatic rifle from his duffel bag and started firing at Transportation Security Administration officers. Gerardo I. Hernandez was fatally shot. He was the first TSA official in the agency's 12-year history to be killed in the line of duty. Friend and former TSA co-worker Kevin Maxwell told KNBC-TV that Hernandez was a family man. Maxwell says Hernandez was proud of his son, who played football. TSA Administrator John Pistole was set to meet with Hernandez's family Saturday afternoon. Fellow screeners and law enforcement officials wore black mourning bands in Hernandez's memory.
