Sgt. Paul Edwards tells WABI-TV (http://bit.ly/125ARCY) that the tractor was hit from behind by an old fire truck Thursday. The driver of the tractor was killed.
The fatal accident happened after the parade was rerouted because of a nearby police standoff with an armed man. Police evacuated an apartment building where a man they described as despondent was holed up and asked parade spectators to stay away from the downtown area.
The man fired about 70 rounds out of a window. He was taken into custody late Thursday morning.
