Questions over the motives behind the shooting at a San Bernardino holiday party Wednesday may be closer to being answered after a Facebook post revealed a pledge of allegiance to Islamic State by the female shooter, Tashfeen Malik, officials said Friday.

The Facebook post is the latest clue for investigators on the motivations for the deadly attack which left 14 dead earlier this week.

The FBI is now treating the deadly shooting rampage as "an act of terrorism."聽

鈥淎s of today, based on the information and facts as we know them,鈥� David Bowdich, the assistant FBI director in charge of the Los Angeles office, said at a Friday news conference. The FBI has taken over as the lead investigative body on the shooting.

According to the Los Angeles Times,

Ms. Malik was born in Pakistan and moved to Saudi Arabia before her engagement to Syed Rizwan Farook. She studied in Pakistan and graduated in 2012 with a degree in pharmacy. According to local officials, her family originated from Karor Lal East in the聽Layyah District of Pakistan's Punjab province.

The couple met online a few years ago and married in Mecca, Saudi Arabia. They returned to Saudi Arabia in the summer of 2014, according to the Saudi Embassy in Washington. The couple was in their late 20s and married last year after Malik gained legal permanent resident status in the United States.

There was no evidence prior to Wednesday's attack that indicated a direct connection to Islamic State militants, leading some investigators to believe that the couple had become self-radicalized. Malik鈥檚 family claims they had no knowledge of her sympathies for the group.

鈥淎t this point we believe they were more self-radicalized and inspired by the group than actually told to do the shooting,鈥� an official told the New York Times, speaking on the condition of anonymity because the investigation is continuing.

鈥淎s far as I know, there was no discussion of any of that [among family members],鈥� Mohammad Abuershaid told the Los Angeles Times. Abuershaid added that Malik鈥檚 family was very conservative but she didn鈥檛 discuss world issues like the Middle East with her in-laws. 鈥淭ashfeen was an invidual who kept to herself most of the time.鈥�

According to senior federal officials, Malik鈥檚 husband, Mr. Farook, was likely in contact with a small handful of alleged extremists,聽including one with al Shabab and another with the Nusra Front in Syria. Together, Malik and Farook amassed a small but deadly arsenal of weapons and explosives in their Redlands home, including pipe bombs and thousands of rounds of ammunition. The firearms were聽all purchased legally.

They fired as many as 150 bullets before being shot by police, killing 14 and injuring 21 more.

鈥淐ertianly they were equipped and they could have continued to do another attack 鈥β燱e intercepted them,鈥� San Bernardino Police Chief Jarrod Burguan said at a news conference Thursday.聽
