The man has been missing since the attack on Wednesday? Nothing suspicious about that…

Via LA Times:

FBI agents raided a Riverside home belonging to a friend of San Bernardino shooter Syed Rizwan Farook as they try to determine whether the man purchased two of the semiautomatic rifles used in the massacre, according to a law enforcement source.

The source, who asked to remain anonymous because the case is ongoing, said officials have been trying to talk to the man to see what he knows. It’s far from clear whether the man had anything to do with the violence or even knew what Farook did with the guns, the source added. A second source said the guns were purchased three years ago.

The person the FBI is seeking to interview is Enrique Marquez Jr., a source said.

Farook, his parents and siblings lived on Tomlinson Avenue for several years before moving out a few months ago. Marquez lived next door.

While Farook generally kept to himself, one exception was his friendship with Marquez, who shared his love of tinkering with cars, neighbors said.

On Thursday, Gustavo Ramirez, who said he was Marquez’s stepfather, told a Times reporter that he and his wife hadn’t heard from Marquez since Wednesday afternoon and were concerned. Ramirez said it was unlike Marquez not to come home.

On Friday, someone had put up a sign in the family’s yard that said: “Please keep off the property thank you.”

The garage door appeared to have been broken, and a window was shattered.

Update:

So the terrorists didn’t buy the rifles themselves, so no, they didn’t ‘obtain them legally’. So even had they been on a list, they would have gotten around it.

Via The Blaze:

Neighbors said authorities with guns drawn broke windows and used a cutting torch to get into the garage. A neighbor said an old friend of Farook’s lives in the house.

A law enforcement official said that more than three years ago, that person bought two high-powered rifles later used in the shooting.

But authorities haven’t been able to talk to him because he checked himself into a mental hospital after the attack. The official was not allowed to discuss the investigation publicly and spoke on condition of anonymity.

The FBI has said the man is not a suspect in shootings, though they want to question him.
