St Louis Rams Stadium Evacuated - Breaking News! AP - St. Louis, MO - Edward Jones Dome Evacuated What was at first believed to be a substance left over from this morning's mock terrorism drill for local emergency response teams led to the evacuation of the Edward Jones Dome in St. Louis today. The Rams' playing field was sealed off for nearly two hours when one of the players, on his way to the locker room, happened to look down and notice a suspicious-looking, unknown white powdery substance on the field. Head coach Mike Martz immediately suspended practice while the FBI was called in to investigate. After a complete field analysis, the FBI determined that the white substance unknown to the players was the goal line. Practice was resumed when FBI Special Agents decided that the team would not be likely to encounter the substance again.
