WASHINGTON — Actor Malcolm-Jamal Warner, known for his role as Theo Huxtable in the “The Cosby Show,” has died, according to multiple media outlets. He was 54. 

Warner died in an accidental drowning Sunday in Costa Rica, according to the Associated Press. TMZ first reported on the “The Cosby Show” alum’s death.

Costa Rica’s Judicial Investigation Department said Monday that Warner drowned Sunday afternoon on a beach on Costa Rica’s Caribbean coast. He was swimming at Playa Grande de Cocles in Limon province when a current pulled him deeper into the ocean.

“He was rescued by people on the beach,” the department’s initial report said, but first responders from Costa Rica’s Red Cross found him without vital signs and he was taken to the morgue.

The 54-year-old actor is best known for his role as Theo Huxtable, the only son of Cosby’s character, on “The Cosby Show.” Warner’s performance earned him a Primetime Emmy nomination for best supporting actor in a comedy in 1986. 

Following his time on “The Cosby Show,” Warner played Malcolm McGee on the 90s’ sitcom “Malcolm & Eddie.” The 54-year-old actor had credits in dozens of television shows over the years, including “Grown-ish,” “9-1-1” and “Alert: Missing Persons Unit.” 

Most recently, the New Jersey native starred as AJ Austin on the medical drama “The Resident.” 

Aside from acting, Warner was a Grammy-winning musician. He won an award for best traditional R&B performance in 2015 and was nominated for a Grammy in 2023 for best spoken world poetry album. 

Last year, Warner launched a podcast alongside Weusi Baraka and Candance Kelly called “Not All Hood,” The podcast explored the diverse experiences of the Black community and representations in media. 

“When we talk about the Black community, we tend to speak of it as a monolith when the reality is there are so many different facets of the Black community, and we wanted to have a space where we can really explore, discuss, and acknowledge all of those different aspects,” Warner said in an interview with People last year

Warner is survived by his wife and daughter, according to People.
