John Amos' cause of death revealed

“Roots” and “Good Times” star John Amos died of heart failure, according to a death certificate obtained by TMZ.

Although death confirms that Amos died back on August 21, his death was only confirmed on Tuesday by his son Kelly Christopher Amos. The actor's daughter learned of her 84-year-old father's death through media reports.

“We are devastated and have many questions about how this happened 45 days ago since, like so many of you, we found out about it through the media,” wrote Shannon Amos in the caption of an Instagram post in which she said this celebrated the life of her late father.

“This should be a time to honor and celebrate his life, but we are struggling to cope with the wave of emotions and uncertainty that his death brings. Still, there is a semblance of peace knowing my father is finally free,” continued Shannon Amos.

The daughter previously accused her brother of elder abuse towards Amos. Earlier this year, an investigation was launched into Kelly Christopher Amos over alleged mistreatment and improper care of the actor. The case was later dropped due to lack of evidence and classified as a family dispute.

Amos' publicist Belinda Foster told CNN he died of natural causes. She also shared a statement from the actor's son via email.

“It is with deep sadness that I inform you that my father has made the transition,” the statement said. “He was a man with the kindest heart and a heart of gold… and he was loved around the world. Many fans consider him to be their TV father. He lived a good life. His legacy will live on in his outstanding work as an actor on television and film.”

Amos was known for playing James Evans Sr. on “Good Times,” but was later removed from the series by Norman Lear after he criticized the all-white writers for inauthentic portrayals of black Americans. He later earned critical acclaim for playing the adult Kunta Kinte in the 1977 adaptation of “Roots.” He also appeared in “Coming to America,” “Alcatraz: The Whole Shocking Story,” “All in the Family,” and “The West Wing” on.
