Chaos erupted near a Broward County preschool Thursday when a Texas man, Joe Edward Ochoa Jr., allegedly attempted to kidnap a child, using the young one as a shield as tensions flared among three men, one of whom brandished a gun. The disturbing scenario, unfolding at Peppermint Academy Preschool located at 7753 Johnson St., Pembroke Pines, saw a mother and her stroller-bound child drawn into a sudden maelstrom of danger.
