The shooting rampage that left 14 people dead in California Wednesday has put a spotlight on violence in the workplace. Investigators are trying to understand why suspected shooters Syed Rizwan Farook and Tashfeen Malik marched into a conference at the Inland Regional Center in San Bernardino and allegedly started shooting.
The shooting took place at a work conference and holiday luncheon for the San Bernardino County Health Department and at least 17 people were also injured. Police said Farook had been a county employee for five years and was at the event earlier Wednesday but left at some point.
