Authorities declined to discuss the gunman's motivation. But a law enforcement official told The Times that a note was found on Ciancia expressing "disappointment in the government" and saying that he had no interest in hurting "innocent people."
Another law enforcement official told The Times that investigators were looking into the possibility that he "wasn't a fan of the TSA."
In the New Jersey neighborhood where Ciancia is from, people described him as shy and a little awkward but said they never saw signs of anger or violent tendencies.
"He kept to himself and ate lunch alone a lot," said David Hamilton, who graduated with Ciancia from Salesianum School in Wilmington, Del., in 2008. "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."
Ciancia lived for a time at an apartment complex on Los Feliz Boulevard in Atwater Village. It's unclear how long he had lived in Los Angeles or what he did for a living.
Marc Kreiner, who owns The Morrison, a restaurant and bar next door to the apartment complex, said he knew Ciancia by sight. He had been into the bar about half a dozen times, he said.
"He was kind of a quiet guy, came in mostly by himself, and one time with a couple of guys," Kreiner said.
Mincey told KCAL that Ciancia had recently moved to Sun Valley, but they had had lunch together as recently as last week.
"He said he was going back to New Jersey, going to work for his dad, making amends with family problems, and spending the holidays with his family. That's all I know," said Mincey.

Neighbors said they would see Ciancia and his brother riding four-wheeled vehicles up and down their long driveway. But tragedy struck the family a few years ago, neighbors said, when Ciancia's mother died after a long illness.
"This is an absolute tragedy, in the highest sense" said Orlando Pagan, a police officer in neighboring Penns Grove. "It was a very good family. Whatever happened, it had nothing to do with their upbringing."
