Rockingham County Sheriff's spokesman Sgt. Kevin Suthard said the two men were still at large Sunday.
Deputies say none of the victims appeared to suffer life-threatening injuries after being gunned down early Saturday at a Moose Lodge in Madison, about 25 miles north of Greensboro.
Deputies say a fight broke out during the party attended by 250 to 300 people. Investigators say witnesses reported that both gunmen attended the party, AP reported.
They covered their faces with ski masks and opened fire before speeding away from the scene in a silver car driven by a woman. The car's make and model aren't known.
