The District's homicide toll for 1988 reached 24 yesterday with the early-morning shooting of a man inside a Southwest nightclub, the shooting of a man in a Southeast apartment and the stabbing of another man on the street in Northwest.

Police had no motives in the deaths and had made no arrests. One year ago at this time, nine homicides had occurred in the District, police said.

George Pringle, 20, of Temple Hills was victim No. 22. Police say a man opened fire at 2:10 a.m. inside the East Side nightclub, 1824 Half St. SW, hitting Pringle and another man, James Ward, 24. Pringle was taken to D.C. General Hospital, where he was pronounced dead. Ward, of 1014 45th St. NE, was in stable condition at D.C. General.

Police said several fights broke out at the club, where hundreds of people were attending a party. They refused to confirm reports that Brian Tribble, who was acquitted of drug charges in the death of University of Maryland basketball star Len Bias, had rented the club for the evening and had put two or three men out of the party.

The 23rd victim -- identified as Horace Lawson Pinnock, 34, of the Bronx, N.Y. -- was shot about 2:25 p.m. in an apartment at 625 K St. SE in the Arthur Capper Dwellings. He also was taken to D.C. General Hospital and died there. "We think drugs are involved," homicide Lt. C.E. Bailey said.

A short time later, an unidentified man was stabbed on the street near 1430 W St. NW. He was taken to Howard University Hospital, where he died from a chest wound. Police are looking for two men who were seen running from the area.
