Lexington police were investigating the Sunday night shooting of a man at Duncan Park.
Police found the 21-year-old victim with a gunshot wound to the head about 6:30 p.m., said Lt. Eddie Hart. The unidentified victim was lying next to the swings at the park playground, Hart said.
"Officers performed CPR on the victim until the fire department arrived," Hart said. An ambulance rushed him to University of Kentucky Chandler Hospital.
"At this time we would consider his injuries critical," Hart said.
Witnesses told police that three to four men were chasing the victim. Others said they saw three or four men run off after the shots were fired, Hart said.
Duncan Park is on Fifth Street between North Limestone and Martin Luther King Boulevard.
Right before the report of the shooting, another disorder involving shots fired from a dark-colored Pontiac Grand Prix or Grand Am was reported at Sixth Street and Martin Luther King Boulevard, Hart said.
"We're looking into if these were related," he said. "Maybe it started down around Sixth and Limestone, and the victim ran from that location and was followed by these subjects."
The victim also might have been a bystander who was not an intended target, Hart said.
"So we're looking into all the possible scenarios," he said.
