Four workers remembered after fireworks explosion

A memorial parade scheduled for Sunday on Ocracoke Island remembered the four workers who died when a truckload of fireworks exploded over the weekend.

The workers were unloading fireworks from the truck when it blew up Saturday morning.

Agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives determined the explosion was an accident.

The crew worked for Melrose South Pyrotechnics Company, near Rock Hill, South Carolina.

The company had been cited for a 2001 explosion at its plant that killed a worker.
