The victims included four members of a Georgia family as well as the driver of the van, who may have suffered a fatal heart attack that caused him to lose control of the vehicle.
Three children and a 50-year-old woman were run down as they walked on the sidewalk in Little Havana following the Marlins' late-afternoon game against the Phillies. Police said the van crashed through a metal handrail outside an apartment-building parking garage before striking the pedestrians.
Another man on a bicycle was also clipped before the van hit the wall of the parking garage but was not seriously injured.
Police told the Miami Herald a distraught man was treated at the scene, but it was not clear if he was related to the victims, whose names were not released.
