The injured also included a four-year-old child.
Shocked witnesses told reporters that the dark-blue sedan deliberately ran down the broadwalk at 60mph, crushing the pedestrians. One witness said the driver of the vehicle was out for blood. Other said people were scattered around the ground, badly injured and bloodied.
Photos taken by security cameras showed people diving out of the killer car.
The driver fled after the incident and is sought under felony hit-and-run charges. One man was reportedly taken to custody although details were yet to be confirmed.
