Very possible:
Police said the two shooters were a married couple: Syed Rizwan Farook, 28, a former county health worker born in the United States, and Tashfeen Malik, 27, a woman described as his Pakistani-born wife. Even as the bloodshed made it among the deadliest mass shootings in recent memory, the attack was also a rarity in another way: Mass shootings are rarely carried out by more than one attacker, and women almost never carry out such assaults.
My wife works for the Ohio Dept of health, and they had to stop having "Christmas" Parties, and instead had to call them Holiday parties, because of the fuss people were making. Not just Muslims, but Athiest as well.
IT is very possible that a similar scenario played out.......
Also people are getting laid off in groups now, something else to think about especially if the both of them might have thought he was being trated unfairly.
Just going to be labeled another case of "workplace violence"...
