Malcolm-Jamal Warner, the actor perhaps best known for starring in the TV sitcom "The Cosby Show" as son Theodore "Theo" Huxtable, has died at 54.

Warner drowned off the coast of Costa Rica on Sunday, Costa Rican National Police told ABC News. Warner's official cause of death was asphyxia, police said. //

In 2023, Warner spoke to media personality Bevy Smith on her podcast "Bevelations" about the legacy of "The Cosby Show." Because of the allegations and subsequent conviction of sexual assault (aggravated indecent assault) by comedian, actor, and producer Bill Cosby, Smith asked Warner whether he felt the legacy of the show was irreversibly tainted. Warner was insightful in his response.

"There's a generation of us who went to college, they sought out higher education because of that show. There's a generation of us that went and got married and had loving relationships with each other and their children because of that show. That impact is irreversible."

Malcolm-Jamal Warner was born August 18, 1970, and trained early in life to be an actor. Warner attended and graduated from The Professional Children's School in New York.
