"Prayers needed. Lot of people hit. A lot killed," firefighter Steve Keys wrote in an emotional Facebook post. One of the first responders at the scene of the shooting, he was performing CPR on a wounded woman when a bullet grazed his chest and stomach. Despite the fact that he was bleeding, Keys stayed on-site and continued helping whoever he could, and was later picked up by a friend and driven to be treated. "I'm ok. But a lot of people aren't. I am lucky," he further wrote.
