Two officials say investigators are looking into whether Tashfeen Malik radicalized her American-born husband and was the driving force in the San Bernardino massacre plot.
That possibility emerged late last week when it was disclosed that the Pakistani-born Malik had pledged allegiance to the Islamic State group in a Facebook post at about the same time she and her husband Syed Farook launched the commando-style attack that killed 14 people.
One U.S. official says there appears to be nothing in Farook's history that would implicate him as the driver of the attack.
Separately, a law enforcement official said investigators are looking into whether Malik was radicalized in the Middle East, where she spent considerable time, and whether she used her 2014 marriage to Farook to penetrate the U.S. and commit jihad. But the official said it is only one among a number of theories that are being pursued.
The two officials were not authorized to discuss the investigation publicly and spoke on condition of anonymity.
More than 100 people gathered for an interfaith memorial service at a mosque where shooter Syed Farook had occasionally prayed. Silver-framed photos of the victims were placed on a table at the Islamic Community Center of Redlands, with a candle lit for each.
Muslim community members at the service in Loma Linda, California, said they are feeling both grief over the loss and fear of a backlash against their community. They encouraged community members to come together and not live in fear.
"It is really sad that we meet because of this. It is sad that only in death are we able to celebrate humanity," 30-year-old mosque member Ajarat Bada said, fighting back tears
