LOS ANGELES (AP) -- 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.
Gerardo Hernandez, the first TSA official in the agency's 12-year history to be killed in the line of duty, is being remembered as a family man who constantly smiled at travelers.
The TSA says it will review its policy on officer safety.
Paul Ciancia is reportedly an unemployed motorcycle mechanic. He was arrested Friday after authorities say he barged into a terminal, pulled an AR-15 semi-automatic rifle from his duffel bag and opened fire.
Ciancia is facing charges of murder and commission of violence at an international airport. If convicted, he could get the death penalty.
