Keisha Knight Pulliam is honoring her former "The Cosby Show" co-star Malcolm-Jamal Warner after his tragic death. In a touching Instagram post on Sunday, Pulliam shared a clip of Warner performing onstage at the City Winery in Atlanta, followed by footage of two young girls, believed to be each of their daughters, walking with a horse on a farm.

Malcolm-Jamal Warner, best known as Bill Cosby's son Theo Huxtable on "The Cosby Show," died after he was swept away by a current, authorities say.

Following the death of Malcolm-Jamal Warner in an accidental drowning in Costa Rica, local Red Cross confirmed a second man was taken to a hospital in critical condition.
