Only one of the boxes caused a full-scale evacuation. Two others were uncovered in the mail rooms of Toyota plants in Texas and West Virginia without incident, while a third was stopped in a post office in Indiana. At this point, it's not clear exactly what made the packages suspicious in the first place. Whatever it was, though, it was enough to cause the post office workers in Indiana to call the state police. Law enforcement has yet to reveal the name of the sender.
