June 6, 1993, began like any other day in the small town of Windsor, North Carolina. By the end of the day, nothing in this community will ever be the same.

As 6 o’clock hits, the employees of the town’s Be-Lo grocery store are going through their closing tasks. A cleaning crew loads their equipment in as they prepare to wax the store’s floor.

What they don’t know is that someone else is in the store with them.

With the sun falling below the horizon, a call is placed to 911. The caller, fighting to get each word out, has been shot. Police descend on the store to find a grisly scene: three people are dead, two more are seriously injured.

The search begins for the killer, an investigation that carries on almost 30 years later. Leads carry police all over the country but the break they so desperately need continues to elude them.
