Days before Paul Ciancia's murderous rampage at LAX, one woman who knows the alleged gunman and his three roommates says Ciancia was already plotting his crime.
CNN's Miguel Marquez reports.
Woman: He asked one of the roommates if you could have a ride to the airport.
Miguel: Why did he need a ride?
Woman: He said he was going back home. He said his dad was sick and he had to go help take care of him.
MM: Did anyone see a ticket?
Woman: No. He also didn't tell him what day he needed to leave.
She says Ciancia rarely left his San Fernando Valley apartment since moving there in January. Describing him as socially awkward and a heavy smoker, he always paid his rent on time and appeared to make money trading online. The day he put his alleged plan into action, she says, took his roommate by surprise.
Ciancia's roommates believe he texted family members in New Jersey, telling them he was going to commit suicide. That prompted frantic calls between police in NJ and LA. Police came to Ciancia's home.
She says the two other roommates were woken up and handcuffed as police searched the premises. Paul already gone and no sign of a gun.
Woman: At this moment as they are seeing this on the TV, their third roommate comes back and he said "Oh I just dropped off Paul at LAX, he had to go home."
And they just knew and said "I think you just dropped off Paul to a shooting."
