"She (Tashfeen Malik) got the visa in Pakistan. I'm sure she got the visa in Pakistan," State Department Deputy Spokesman Mark Toner told reporters at his daily news conference yesterday.

Tashfeen Malik's parents had immigrated from Pakistan. She along with her husband Syed Rizwan Farook were involved in a mass shooting at a holiday party in San Bernardino that killed 14 people and injured at least 17, the police said.

K-1 visa becomes null and void if the marriage is not done within the stipulated 90 days. Farook's brother-in-law, Farhan Khan, said the couple got married two years ago.

Farook was a US citizen, while Tashfeen was in the US on a Pakistani passport and had a K1 'fiance visa', according to David Bowdich, assistant director of the Los Angeles Federal Bureau of Investigation (FBI) office.

Farook, son of an immigrant from Pakistan, was born in the US and was working as an environmental health specialist for San Bernardino County.

On Wednesday the couple left their six month old daughter at the home of their parents, and then went on a shooting spree at the holiday party of his own office.
