'The Cosby Show' star Malcolm-Jamal Warner dies at 54

(NewsNation) — "The Cosby Show" alum Malcolm-Jamal Warner has died. He was 54.

According to People Magazine, Warner was on a family vacation in Costa Rica and reportedly drowned while swimming. Costa Rican authorities later confirmed he died as a result of an accidental drowning Sunday afternoon when a current pulled him deeper into the ocean on a beach on the country's Caribbean coast.

An initial report from authorities obtained by the Associated Press said he was rescued by people on the beach, but first responders found him without vital signs and was taken to the morgue.

Warner was best known for portraying Theo Huxtable, the only son of Cliff and Clair Huxtable, in "The Cosby Show" from 1984 to 1992, which earned him an Emmy nomination in 1986 for supporting actor in a comedy.

After "The Cosby Show," Warner went on to star alongside comedian Eddie Griffin in the UPN Network television series "Malcolm and Eddie" from 1996 to 2000. He is also well-known for his role in the 2011-2015 series "Reed Between the Lines," where he starred opposite Tracee Ellis Ross.

According to Warner's IMDb page, he has also starred in episodes of "Major Crimes" as Chuck Cooper, "Suits" as Julius Rowe and AJ Austin in "The Resident."

Last June, Warner started a podcast called "Not All Hood" with cohosts Weusi Baraka and Candace Kelley, telling People it was a space where he could be his "most vulnerable."

Aside from acting, Warner won a Grammy in 2015 for best traditional R&B performance, and was nominated for best spoken word poetry album for “Hiding in Plain View.”

He is survived by his wife and daughter, according to TMZ. Warner's representatives have declined immediate comment.
