As the FBI combs through the crime scene at Los Angeles International Airport, where a gunman opened fire on Friday, killing a TSA agent and hurting others, Terminal 3 remains closed.
The airport tweeted that 826 scheduled flights and 99,200 passengers were affected by the incident. Flights scheduled to leave from Terminal 3 are leaving from other terminals.
Meanwhile, we are learning a little more about the gunman and his victims. Here's an overview:
-- Friends told The Los Angeles Times that Paul Anthony Ciancia, 23, was a quiet teenager who kept to himself.
"I really don't remember any one person who was close to him.... In four years, I never heard a word out of his mouth," David Hamilton, who graduated from a Delaware high school with Ciancia, told the paper.
-- Quoting two federal law enforcement officials, USA Today reports that investigators discovered a note in the alleged shooter's bag that detailed "an intent to 'kill' TSA officers."
The note, the paper reports, hinted at some kind of suicide mission.
-- The Los Angeles Times described the note as containing "anti-government" text.
-- The AP quotes Pennsville Township, N.J., Police Chief Allen Cummings as saying that Ciancia's father called police Friday because he was worried that his son intended to take his own life.
Ciancia's father, Cummings said, had received a text message that worried him.
-- Gerardo I. Hernandez, 39, is the first TSA agent to lose his life on the job.
"No words can explain the horror that we experienced today when a shooter took the life of a member of our family and injured two TSA officers at Los Angeles International Airport," TSA administrator John S. Pistole said in a statement.
NBC Los Angeles spoke to Kevin Maxwell, a friend of Hernandez. He said Hernandez always talked about his family:
"The victim was 'very proud' of his son and 'spoke profoundly' of his daughter, his friend and former colleague said.
"Maxwell said he worked with Hernandez in TSA's logistics department until last year, when Maxwell resigned from his position to care for his grandmother."
-- The New York Times reports two other people and at least four others were injured during the incident.
-- CNN reports that witness reports could give us a clue as to motive:
"Some said the gunmen asked people, 'Hey, are you TSA?' — the acronym for the Transportation Security Administration. If they said 'no,' he would move on.
"One of those questioned travelers was Leon Saryan. He told CNN's Anderson Cooper that the same man he'd just seen shoot a TSA officer 'calmly' walked toward him and asked, 'TSA?'
"'I just shook my head,' Saryan said. 'And he kept going.'"
-- The New York Times spoke to Rich Garry, 68, of Fullerton, Calif., who said he had just cleared security when he heard two pops and saw a TSA agent on the floor.
The paper adds:
"As the gunman moved through the terminal, Mr. Garry said, 'he was very calm. When he got to the top of the stairs where the security checkpoints are, he looked around. If he would have come up the ramp, he would have had a field day with all the people lying on the ground, like me.'
"Mr. Garry said he and several others crawled to a nearby elevator and went to the ground floor. Once there, he saw police officers for the first time, and told them to go to the second floor."
