Akeem Juan Jones, of Dunn, got into an altercation with other people during the party at 139 Bears Lane around 1:40 a.m., said Maj. Gary McNeil.
Jones was shot during the fight, and family members took him to Betsy Johnson Hospital, McNeil said. Doctors pronounced him dead upon arrival.
While Jones was at the hospital, a large number of people gathered outside it, McNeil said. He did not have an estimate of how many.
Investigators do not have any suspects and have not established a motive. They could not confirm if the shooting or gathering were gang related.
Anyone with information about the case should contact the Harnett County Sheriff’s Office at 910-893-9111.
