Description:At 32 years old, Belkis Ayon was already one of Cuba's most famous artists.
Her dark, haunting prints drew on Afro-Cuban religious beliefs and in particular an all-male secret society called abakua. But then, on Sept. 11, 1999, she committed suicide. Her friends and family still don't know why. Now a major retrospective exhibit has opened in Havana's San Francisco de Asis cathedral.(3:42)
