SENTENCED. MARK MANES, 22, to six- and three-year prison terms for selling a handgun to Dylan Klebold, one of the teens responsible for the massacre at Columbine, and for possessing a sawed-off shotgun; in Golden, Colo. At the sentencing hearing, transcripts of a videotape were read in which the killers thank Manes for "[helping] us do what we needed to do" but say he knew nothing about their plans.

RESIGNED. MICHEL CAMDESSUS, 67, managing director of the International Monetary Fund who helped stabilize Mexico and Asia in recent crises; in mid-term, for personal reasons; in Washington.

DIED. LESTER BOWIE, 58, theatrical avant-garde jazz trumpeter and founding member of the Art Ensemble of Chicago; of liver cancer; in Brooklyn, New York. A key voice in the experimental-jazz movement of the 1960s in Chicago, Bowie recorded and performed in Europe and the U.S. for 35 years--often in his trademark white coat.

DIED. RICHARD MARTIN, 52, erudite curator of the Costume Institute at New York's Metropolitan Museum of Art; of melanoma; in New York City. A former F.I.T. art-history professor, Martin combined scholarship and pop culture to invigorate the Costume Institute. Among his recent shows: Wordrobe, a retrospective of clothing decorated with words.

DIED. JACOBO TIMERMAN, 76, voluble Argentine journalist and activist imprisoned and tortured by military forces after the 1976 overthrow of President Isabel Peron; of a heart attack; in Buenos Aires. Timerman's 1981 best seller, Prisoner Without a Name, Cell Without a Number, sparked international outrage over human-rights abuses.

DIED. ALFRED GWYNNE VANDERBILT, 87, horse-racing legend and scion of Commodore Cornelius Vanderbilt; in Mill Neck, N.Y., after returning from his daily visit to the Belmont racetrack. Vanderbilt was the consummate sportsman aristocrat and society high flyer. The owner of the great Thoroughbred Native Dancer, he helped introduce the use of the starting gate and the photo-finish camera.
