The primary shooter, Sayeed Rizwan Farook, age 28, was American-born to parents who were from Karachi, Pakistan, and was described as "a very devout Muslim".

He recently traveled to Saudi Arabia.

According to The Daily Mail, "Farook graduated from California State University, San Bernardino with a degree in environmental health in 2009."

The second shooter killed in the shootout was Farook's wife Tashfeen Malik, a pharmacist, age 27, born in Pakistan but more recently a resident of Saudi Arabia, who had married Farook two years ago.

The long guns used in the attack are banned in California, both by description of their configuration. Farook most certainly did not just walk into a California gun shop or a gun show and buy them in that configuration. ALL long guns less than 50 years old are banned from private party sales in California, and to legally possess a banned-configuration "grandfathered" semi-auto rifle in California, it would have had to have been registered to Farook on or before December 31, 1999. But he was 13 years old in 1999, so that is impossible.
