Shooting broke out as about 100 guests were leaving the City Grill restaurant in the early hours of August 14.

Two men and two women were killed, and four more people were injured.

A 25-year-old man named Keith Johnson was later arrested after a major police operation and charged with four counts of second-degree murder.

The victims have not been officially named, but relatives of those killed have been speaking to local journalists.

Raymond Wilhite, who says his daughter Tiffany was killed, called it a "senseless" incident.

"This kind of thing just has to stop," he said.

"Her sister and her brother could see her right here. When they lifted up the cover they could tell it was her because they knew what she was wearing."

Witnesses said they believed some men had become angry after being refused entry to the party.

The restaurant's managers had decided to close up when an argument broke out.
