FBI returns to apartment of Los Angeles airport shooting suspect, escorts man away

The FBI has revisited the apartment of the suspect charged with killing a TSA officer during an attack at the Los Angeles airport.

At least one FBI agent was at the Sun Valley apartment on Monday — the same duplex that agents searched Friday after the attack that killed TSA officer Gerardo Hernandez.

A man was escorted out of the apartment and drove away in a black Hyundai — the type of car that authorities say an unwitting friend used to give Paul Ciancia a lift to the airport minutes before Friday's rampage.

However, the FBI wouldn't identify the man or discuss the investigation.

Neighbors say they remembered little or nothing about Ciancia. Some did not even recognize his photograph and one said simply that he was quiet.
