One of the main stars of the hit 1980s sitcom The Cosby Show has reportedly died tragically. Malcolm-Jamal Warner, who played Theo Huxtable on the iconic television program, has died at 54, according to multiple reports.

Cosby agreed and was deposed by Constand’s lawyers over four days in 2005 and 2006 (resulting in more than 1,000 pages of testimony). The lawsuit was eventually settled out of court for a then-undisclosed amount, Cosby’s deposition was sealed and both parties signed non-disclosure agreements, according to The New York Times.

An unconfirmed source shared that it’s believed that he died as a result of an accidental drowning, but details and official confirmation are still developing.
