Saira Khan, Syed Farook's sister and Tashfeen Malik's sister-in-law, told ABC News that she wants to adopt the couple's six-month-old baby girl. 

She explained that they could give the orphaned baby 'a stable upbringing.' 

'For the time being, we want her to enjoy her innocence,' Khan told ABC News.

'You know, we don't want her to know everything, but I think eventually she will find out probably on her own.

'It's harder for us to understand, especially knowing that he was our brother and he was so happy with her.

'How can he leave his only child, you know? And how could the mother do this?'

San Bernardino County Sheriff John McMahon told ABC News 'federal authorities, in conjunction with the county's child protective services, took custody of that child, and at some point in the next week, they will have a dependency hearing in the County of San Bernardino to determine where, ultimately, that child will live, at least in the short term.'

Khan added that she hopes to have her niece by Monday. She is already the mother to a two-year-old girl and a seven-year-old boy with her husband.

New details have emerged about the radicalization of Malik, a Pakistani woman who along with her American husband, killed 14 people in San Bernardino, California and pledged allegiance to ISIS.

Malik who moved to the US last year when she married Syed Rizwan Farook, 28, had spent most of her life in Saudi Arabia and relatives say she became more conservative about her Muslim faith three years ago.

Relatives of Malik in Pakistan who are estranged from their wealthy family members who live in Saudi Arabia said that she used to wear Western-style clothing but later switched to more traditional garments such as a burka, which covers the the entire body.

'I recently heard it from relatives that she has become a religious person and she often tells people to live according to the teachings of Islam,' Hifza Batool, 35, said of his step-niece, whose age is either 27 or 29.

Saudi Arabia requires the wearing of a hijab, but does not mandate burkas. Pakistan, where Malik returned to study at Bahuddin Zakri University in Multan, does not have a dress code for women.

Batool said that he had not ever actually met Malik because, 'Tashfreen Malik's parents are rich and we are poor and they don't like to meet with their poor relatives'.

Investigators looking into the attack at the San Bernardino disability center where Malik and her husband opened fire are now looking into the massacre as an act of terrorism.

Terrorist group ISIS announced in an online radio broadcast that two of their followers had carried out the attack in San Bernardino on Wednesday before dying in a shootout with police.

'Two followers of Islamic State attacked several days ago a center in San Bernardino in California,' the group's daily broadcast al-Bayan said.

US government sources have said that there is no evidence the attack was directed by the militant group, or that the organization even knew who the attackers were.  

How the couple became radicalized enough to open fire at a holiday party for San Bernardino County employees is still unknown, though some suspect that Malik may have pushed her husband towards extremism. 

According to Fox News, it is believed that on at least one of Farook's two trips to Saudi Arabia in 2013 and 2014, one or both of the spouses reached out to suspected members of al Qaeda. 

The LA Times reported that police sources said Farook also had some form of contact Al Nusra Front, an Al-Qaeda backed group in Syria, as well as al Shabaab in Somalia.

Sources have told Daily Mail Online that US officials communicated with their Pakistani counterparts about connections between Malik and the Red Mosque in Islamabad, which is known for radicalism.

It was at the center of a bloody siege in 2007 as fundamentalists clashed with security forces for eight days.
