Syed Farook and Tashfeen Malik, who killed 14 people in last week’s attack in San Bernardino, California, had communicated with "people with extremist views" in the Los Angeles area, MSNBC reported on Tuesday.

The network reported that the two were "in communication with people with extremist views in the L.A. area. Police have confirmed that through ... electronic communications."

Meanwhile, CNN quoted on Tuesday two American officials who said that Farook may have been plotting an earlier attack in California with someone else.

One official who spoke to the network said the two conspired in 2012 and a specific target was considered. Neither of the officials could say how serious the plotting got.

One official said the two decided not to go through with the earlier attack after a round of terror-related arrests in the area.

"They got spooked," the official said.

Since last Wednesday’s attack, more and more details have slowly been emerging about Farook and Malik.

On Monday,  the FBI said Farook and Malik were both radicalized "for quite some time" and had taken target practice at Los Angeles-area shooting ranges, and once "within days" of the massacre.

Later on Monday, reports said a $28,500 deposit was made to Farook’s bank account on or about November 18, some two weeks before the shooting.

It is believed Farook had contact with people from at least two terrorist organizations overseas, and investigators have also said Malik had pledged allegiance to the Islamic State (ISIS) group in a Facebook posting.
