A year after attack in San Bernardino, faithful seek unity

Federal investigators say the terror attack that left 14 people dead one year ago in San Bernardino may have been triggered by a training session and mandatory attendance at a county Christmas party.

San Bernardino terrorist Syed Farook shot up his co-workers because he was humiliated over having to attend a mandatory Christmas-themed lunch, where he was coerced to pose for a group photo in front of a decorated tree, the Federal Bureau of Investigation said.

US ABC News' investigative team discovered emails between Farook and his Pakistani wife, Tashfeen Malik, which indicate she was upset her Muslim husband was being forced to attend a Christmas gathering.

Farook had been required to go to a similar holiday event with his co-workers and Malik wrote she was furious that the couple had to attend an event centered around Christianity, according to the San Bernardino Sheriffs Department.

It is now believed that they tried repeatedly to detonate three pipe bombs that they had planted in the building. An Ignorant ISIS Pledge Shortly after the attack, the couple posted an online message pledging their allegiance to the ISIS terrorist group and its leader, Abu Bakr al-Baghdadi.
