San Bernardino Killers May Have Planned Further Attacks, Weapons Stockpile Suggests

UPDATED 4.30PM EST - The interior minister of Pakistan said that he does not believe there is a link between Pakistani militants and Tashfeen Malik. "She studied here (in Pakistan) in a university but there is no evidence found in the investigation so far that could link her (Malik) with Islamic militants," Chaudhry Nisar Ali Khan told reporters on Sunday.

Original story - The killings that took place in San Bernardino, California, on Wednesday may not have been the only attack Tashfeen Malik and her husband had planned, officials said Sunday. Reuters quoted an unnamed "senior U.S. government source" saying the weapons cache the couple had collected suggested the pair planned further attacks, but no evidence of specific targets has been found.

The attack, which left 14 dead, has shocked Malik's family. An anonymous relative spoke to the Los Angeles Times Sunday, describing her as a "modern girl" who started to post extreme messages on her Facebook account after arriving in the U.S.

Hafza Batool, Malik's aunt, told the BBC the family is in shock. "She was so modern. I do not know what had happened to her. She brought a bad name to our family," she said.

Malik, born in Pakistan, moved to Saudi Arabia when she was a child. She returned to Pakistan to study pharmacy at Bahauddin Zakaria university in 2007, before moving back to Saudi Arabia in 2012. She met her husband, Syed Rizwan Farook, online. Officials are investigating whether Malik was radicalized abroad or whether she influenced her husband.

"There's a serious investigation ongoing into what she was doing in Pakistan and in Saudi," Rep. Michael McCaul, R-Texas, chairman of the House Homeland Security Committee, said on "Fox News Sunday." "We think that she had a lot to do with the radicalization process and perhaps with Mr. Farook's radicalization from within the United States."

McCaul said Malik, 29, is the "wild card" in the investigation, and that authorities are investigating where the couple got the money to buy the guns.

The attack has prompted sharp response from the 2016 presidential candidates. Democrat Hillary Clinton said private companies need to do more to aid authorities in clamping down on radicalization, while Republican candidate Donald Trump said the use of the word "mastermind" to describe the organizers of the attacks was inappropriate.
