Levi Miller, who works at the FedEx building where a gunman killed at least eight people before taking his own life, tells TODAY he was eating with friends outside the building at 11 p.m. when he heard shooting inside the building. He says he saw “a hooded figure … with an AR in his hand” and ducked for cover. He says one of his co-workers said the shooter was “a well-known worker at this facility.”
