Lighted pylons at the Century Boulevard entrance to Los Angeles International Airport, which normally flash in a multicolored sequence, shine a steady blue Saturday evening, Nov. 2, 2013, in honor of Gerardo Hernandez, the Transportation Security Administration officer slain at an LAX terminal Friday. He is the first TSA officer to die in the line of duty in the history of the 12-year-old agency, created in the aftermath of the Sept. 11, 2001 terrorist attacks.

LOS ANGELES – The 23-year-old gunman charged in a deadly shooting at Los Angeles International Airport told authorities as he was arrested that he acted alone and had been dropped off at the airport by a friend.
A law enforcement official who has been briefed on the investigation told The Associated Press on Sunday that suspect Paul Ciancia was heavily sedated and being watched by an armed guard at the hospital after being shot by airport police in the Friday rampage.
The official requested anonymity and is not authorized to speak publicly.
A TSA officer was killed and five others wounded, including two TSA workers and the gunman himself.
Authorities found a note in the suspect's duffel bag that talked about killing TSA agents and mentioned how easy it is to get a gun.
