In addition, the law enforcement source said investigators have a greater focus on whether the shooting occurred after a workplace issue with religion.
Authorities also haven't ruled out what President Barack Obama called "mixed motives," meaning that Islamic radicalism and workplace grievances both could have driven the attack.
The Farook family lawyers didn't speculate, though Chesley did say that "at some times co-workers have done silly things, like made fun of Syed's beard."
One of Farook's colleagues, Nicholas Thalasinos, liked to discuss religion and politics. He was one of the people killed in the Wednesday attack.
Farook and Thalasinos, reportedly a devout Messianic Jew, once had a "heated, passionate" discussion, said Kuuleme Stephens, a friend of Thalasinos, who had called him at work.

So basically they are trying to make this out to the guy had an issue with someone else during a discussion about religion and this set him off and caused him to become radical. Amazing, just amazing.
