Days after the San Bernardino mass shooting on Wednesday the Islamic State terror group, commonly known as ISIS, released a statement praising the shooters for committing an egregious act of terrorism on U.S. soil.

The massacre occurred on the morning of Dec. 2, when Syed Rizwan Farook and his wife, Tashfeen Malik, opened fire at the Inland Regional Center during a Christmas party, killing 14 people and wounding 21 others. Both suspects were killed during a shootout with police after the attack.

On Saturday, ISIS hailed the shooters as their "supporters," but the group did not take responsibility for the attack, nor did they say that the couple was part of their network, reports CNN.

"We pray to God to accept them as martyrs," ISIS' al-Bayan Radio declared.

Moments after their attack, Malik made a public declaration of allegiance to ISIS leader Abu Bakr al-Baghdadi on her Facebook page, which has since been removed from public view.

Although there is no hard evidence that Malik was the leader of a terrorist conspiracy, law enforcement officials told ABC News that they are being led to believe that she may have been the "mastermind" behind the shooting. Officials also believe that her ability to use assault-style weapons is a signal that she "had some training."

Malik was born in Pakistan but moved to Saudi Arabia when she was 4 years old. She later moved back to Pakistan around 2007, where she attended Bahuddin Zakri University in Multan. She was described as a brilliant student and was not known to have religious or political affiliation during her college career. A Pakistani intelligence official says she stayed in the country until 2012.

On Friday, an attorney representing Farook's family said that Malik met her husband on a dating website. She gained legal permanent resident status in America after obtaining a K-1 visa for fiancées in July 2014. CBS reports that she passed the Homeland Security's "counterterrorism screening as part of her vetting" process before receiving a visa.

She then married 28-year-old Farook, who was born in Chicago to Pakistani parents, on Aug. 16, 2014. The couple had a 6-month-old daughter who was left in the care of a relative on the day of their attack.

A step-aunt of Malik's in Pakistan told The Associated Press that she witnessed Malik gradually become more zealous in her faith within the last three years. Not only did she stop wearing western clothes, but she also began wearing the hijab and, eventually, a burka.
