FBI: San Bernardino shooting investigated as act of terrorism

SAN BERNARDINO, Calif. -- The FBI announced Friday that it is investigating the mass shooting at a Southern California office party as an act of terrorism, but the agency's director said there is no indication the husband and wife who killed 14 people were part of a larger plot or members of a terror cell.

If the investigation confirms those initial suspicions, the attack would be the deadliest inspired by Islamic extremism on U.S. soil since Sept. 11.

While authorities did not cite specific evidence that led them to the terrorism focus, a U.S. law enforcement official said that the wife, Tashfeen Malik, had under a Facebook alias pledged allegiance to the Islamic State group and its leader. A Facebook official said Malik praised Islamic State in a post at 11 a.m. Wednesday, around the time the couple stormed a San Bernardino social service center and opened fire.

Malik and her husband, Syed Farook, died in a fierce gunbattle with authorities several hours after their commando-style assault on a gathering of Farook's colleagues from San Bernardino County's health department.

An Islamic State-affiliated news service called Malik and Farook "supporters" of their Islamist cause but stopped short of claiming responsibility for the attack.

FBI Director James Comey would not discuss whether anyone affiliated with ISIS communicated back to Malik, but he said there was no indication yet that the plot was directed by any other foreign terror group. He also declined to rule out that future possibility.

"The investigation so far has developed indications of radicalization by the killers and of potential inspiration by foreign terrorist organizations," Comey said. He cautioned that the investigation has not yet shown evidence the couple was part of a larger group.

Despite mounting signs of the couple's radicalization, there "is a lot of evidence that doesn't quite make sense," Comey said in a nod to the fact that the investigation was just two days old.

Attorneys representing Farook's family urged the public and media to wait for specific evidence before jumping to conclusions. They said none of his relatives had any indication either Farook or his wife held extremist views.

David Bowdich, head of the FBI's Los Angeles office, said "a number of pieces of evidence" point to terrorism and that the agency was focused on that idea "for good reason." He would not elaborate.

The U.S. official who revealed the Facebook post was not authorized to discuss the case publicly and spoke on condition of anonymity. The Facebook official, who also spoke on condition of anonymity because the person was not allowed under corporate policy to be quoted by name, said the company discovered Wednesday's post on Thursday, removed the profile from public view and reported its contents to law enforcement.

Bowdich said he was not aware of the IS-affiliated Aamaq news service report but was not surprised IS would attempt to link itself to the attack. He said investigators were looking carefully to determine if there is an IS connection.

Farook and Malik rented a townhome where investigators said they found an arsenal of ammunition and homemade bombs. On Friday morning, the property's owner allowed reporters inside in an unusual scene broadcast live on cable TV.

Bowdich said the FBI was done with the scene. Analysts were trying to retrieve data from two cellphones found nearby that had been crushed in an apparent attempt to destroy the information inside.

"We hope that will take us to their motivation," he said.

Until Friday, federal and local law enforcement officials said terrorism was a possibility but that the violence could have stemmed from a workplace grudge.

Attorneys for Farook's family urged the public not to rush to judgment.

"If the most evidence there is to any affiliation is a Facebook account under another person's name ... then that's hardly anything at all," attorney David Chesley said.

Chesley and another attorney described Malik as a housewife who closely followed religious traditions. They said Farook's mother, who lived with the couple, never saw any of the weapons or bombs authorities found. The FBI questioned her Wednesday night and, according to the attorneys, said they would not release her until Farook's siblings came for questioning.

The couple's orphaned 6-month-old daughter is in the care of child protective services and the family will try to recover her next week.

Farook had no criminal record, and neither he nor his wife was under scrutiny by local or federal law enforcement before the attack, authorities said.

Malik, 27, was a Pakistani who grew up in Saudi Arabia and came to the U.S. in 2014 on a fiance visa. Farook, a 28-year-old restaurant health inspector for the county, was born in Chicago to Pakistani parents and raised in Southern California.

Law enforcement officials have long warned that Americans acting in sympathy with Islamic extremists - though not on direct orders - could launch an attack inside the U.S. Using slick propaganda, the Islamic State in particular has urged sympathizers worldwide to commit violence in their countries.

Others have done so. In May, just before he attacked a gathering in Texas of people drawing cartoons of the Prophet Muhammad, a Phoenix man tweeted his hope that Allah would view him as a holy warrior.

Two weeks ago, with Americans on edge over the Islamic State attacks in Paris that left 130 people dead, Comey said that U.S. authorities had no specific or credible intelligence pointing to an attack on American soil.

Since March 2014, 71 people have been charged in the U.S. in connection with supporting ISIS, including 56 this year, according to a recent report from the George Washington University Program on Extremism. Though most are men, "women are taking an increasingly prominent role in the jihadist world," the report said.

It was not immediately clear whether Malik exhibited any support for radical Islamists before she arrived in the U.S. - or, like scores of others arrested by the FBI, became radicalized through online or in-person associations after arriving.

Friends of the soft-spoken Farook who knew him from his daily prayers at a mosque in San Bernardino said they saw nothing to make them think he was violent. They said Farook reported meeting his future wife online.

To receive her visa, Malik was subjected to a vetting process the U.S. government describes as vigorous. It includes in-person interviews, fingerprints, checks against terrorist watch lists and reviews of her family members, travel history and places where she lived and worked.

Foreigners applying from countries that are home to Islamic extremists - such as Pakistan - undergo additional scrutiny before the State Department and Homeland Security approve their applications.

Pakistani officials said Malik moved with her family to Saudi Arabia as a young child. A person close to the Saudi government said Malik eventually returned to Pakistan. The person was not authorized to speak publicly, and did so on condition of anonymity.

Inside the couple's townhome, reporters found a copy of the Quran on a living room table along with several documents, including one that authorities left behind listing what they had seized. Walls were covered with decorative rugs with Arabic script.

An upstairs bedroom had personal documents, a crib and boxes of diapers.
