Two people were killed Sunday in a shooting at a bar in Hartsville, South Carolina, Darlington County Coroner Todd Hardee said.

The shooting happened shortly after midnight Sunday morning at Mac’s Lounge, about a half mile from Coker College.

Earlier, Hardee said five other people had been shot and wounded. But later Sunday, Hartsville city spokeswoman Lauren Baker revised that number to four other people shot and wounded.

Both of those killed were young men, Hardee said. One was found outside on the patio of the bar, and the other was found inside, Hardee said.

No arrests have been made, Baker said.

The motive remains unclear.
