He had money in his wallet at the time he was seen, Cooper said. It also appeared that he was alone at the time, he said.
Dolin had suffered severe head trauma. He was taken to Charleston Area Medical Center's General Hospital, where he is still recovering from his injuries, Hodges said.
Dolin was listed as critical on Friday. He underwent surgery for his injuries, Cooper said.
"He's doing much better now," Hodges said.
Officers still don't know if a weapon was used in the attack or if Dolin's attacker followed him out of the bar, Hodges said.
Charleston Police Chief Brent Webster said such incidents occur on occasion despite regular police patrols. Patrolling areas where there is nightlife always creates challenges, he added.
"We don't want to have crime like that anywhere in the city," Webster said. "But occasionally it does happen."
