Fedex released a statement early Friday saying it is cooperating with authorities and working to get more information.
“We are aware of the tragic shooting at our FedEx Ground facility near the Indianapolis airport. Safety is our top priority, and our thoughts are with all those who are affected,” the statement said.
Live video from news outlets at the scene showed crime scene tape in the parking lot outside the facility.
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.
