@foxnews: A Marine Corps veteran working security at a Tampa Citibank campus ran toward gunfire and confronted a gunman who had just fatally shot a woman outside the building. Hillsborough County Sheriff Chad Chronister describes how the security officer, who also serves as a vice president of operations, took a tactical position inside a men’s restroom and came face-to-face with the armed suspect. The two exchanged gunfire, and the security officer struck the gunman five times. Authorities say roughly 3,200 employees were on campus when the suspect crashed through a courtyard gate, opened fire on a woman and entered the building.
