Bill Cosby mourns demise of his 'The Cosby Show' co-star Malcolm-Jamal Warner

Warner died in an accidental drowning. More details regarding his demise have not been disclosed yet. The actor played the only son of Bill Cosby's character, Heathcliff Huxtable, in the sitcom from 1984 to 1992.

The 88-year-old's rep, Andrew Wyatt, shared that when Cosby received the call of Warner's demise, it was as shocking and painful for him as when he learned of his own son Ennis Cosby's 1997 murder, which was the result of a failed robbery attempt, reported E! News.

Wyatt also shared that Cosby spoke of his late son and Warner playing together as children, noting they "were amazing together."

According to the representative, Cosby believed that Warner left an everlasting impact with his work. He also talked about Warner's work ethic on the set of The Cosby Show.

"You could depend on Malcolm always going to the shelter, to learn his lines, to gather his character to come out and be ready," said Cosby, adding, "When the news came, it was shocking."

He added, "Of course, my thoughts went straight to his mother, who worked so hard. She was so wonderful with him."

Before his demise, Warner was vacationing in Costa Rica and was swimming in the ocean on July 20, Costa Rica's Judicial Investigation Agency confirmed to E! News in a statement.

"The man was rescued by bystanders and taken to shore, where he received treatment from the Costa Rican Red Cross. However, he was declared lifeless at the scene."

Later, Costa Rican National Police confirmed to ABC News that Warner's cause of death was asphyxia, a condition where the body is deprived of oxygen that can be caused by drowning, reported E! News.
