FedEx released a statement to NBC News early Friday morning. “We are aware of the tragic shooting at our FedEx Ground facility near the Indianapolis airport," it read. "Safety is our top priority, and our thoughts are with all those who are affected. We are working to gather more information and are cooperating with investigating authorities.” A witness who said he works at the facility told WISH-TV that he saw a man with a gun after hearing several gunshots. “I saw a man with a submachine gun of some sort, an automatic rifle, and he was firing in the open,” Jeremiah Miller said.
