San Bernardino shooting: Everything we know about Tashfeen Malik

No other targets have been identified, Reuters reports, but their arsenal, including a large number of pipe bombs, shows that the couple wanted to do far more damage than they were able to achieve. The FBI said it is investigating the rampage as a terrorist attack.

Authorities didn’t cite specific evidence that led them to the terrorism focus, but a USA law enforcement official said the wife, Tashfeen Malik, under a Facebook alias had pledged allegiance to the Islamic State group and its leader.

On Thursday, a US intelligence official said Farook had been in contact with known Islamic extremists on social media.

A law enforcement official said it appeared the San Bernardino attack may have been inspired by ISIS, but none of the officials said that ISIS directed or ordered the attack.

[I}n their final days, Mr. Farook and Ms. Malik tried to erase their electronic footprints, another sign of premeditation.

The IS-affiliated news service Aamaq called Malik and Farook “supporters” of their cause but stopped short of claiming responsibility for the attack.

“I know it was in a general timeline where that post was made, and yes, there was a pledge of allegiance”, David Bowdich, assistant director of the Federal Bureau of Investigation’s Los Angeles office, told a news conference about a reported loyalty pledge posted on Facebook by Malik on the day of the attack.

Malik met her husband on a marriage website, and when she came to the USA, she lived as a “soft-spoken” housewife, the attorneys revealed Friday. At one point, she said, she saw two people she knew to be living in the house standing on the front lawn in handcuffs. The couple left their 6-month-daughter with Farook’s mother before going on the attack, according to a relative.

Javier Lesaca, a terrorism expert at George Washington University, told dpa the attack would fit with Islamic State efforts to use social media and the internet to inspire so-called lone wolf extremists to commit attacks overseas.

It was on Farook’s second return trip from Saudi Arabia that Malik entered the United States, said Kuko, who officiated the couple’s USA marital ceremony at his mosque in 2014.

“The reason for that is that the investigation so far has developed indications of radicalization by the killers and of potential inspiration by foreign terrorist organizations”, he said. The pair were killed a few hours later in a shootout with police.

He said his brother, Malik’s father, had become considerably more conservative since moving with his family to Saudi Arabia a quarter century ago.

The Khans, who have a 2-year-old girl and 7-year-old boy of their own, told ABC News they hope to have their niece by Monday.

“From what we heard, they lived differently, their mindset is different”. She said the case should cause people to rethink some of their assumptions about extremism.

Watch Jansing’s interview with Khan, as aired on Friday, below. Police said the couple fired 76 rifle rounds; police fired 380. The neighbor who did not want to give her name said the search lasted until roughly 9 a.m., and that the agents used a blow torch and had dogs with them.
