Police said a black man was seen fleeing the area with a handgun, although no suspects had been into taken into custody by early Sunday evening and the circumstances of the shooting remained unclear.
The shooting occurred Sunday afternoon shortly after the 86th annual St. Paul's Carnival Association parade in Pass Christian, on Mississippi’s Gulf Coast.
