Legendary radio personality Casey Kasem has passed away at the age of 82.

Kasem's daughter, Kerri, posted the sad news to Facebook Sunday morning (June 15).

 

Kasem was best known for his decades as the host of 'American Top 40,' and he was also a talented voice-over artist who provided the voice of Shaggy in the 'Scooby-Doo' animated television series.

Inducted into the National Broadcasters Hall of Fame in 1985, Kasem continued his busy schedule until his retirement in 2009. Recently he had suffered from advanced Parkinson's disease and dementia.

According to TMZ, his three children from his first marriage have been locked in a bitter battle with Kasem's wife, Jean, claiming she blocked them from seeing him for several months. Kerri even accused Jean of elder abuse after she allegedly removed Kasem forcibly from a convalescent home and took him on a multi-state car ride to keep him away from his family.

On Wednesday (June 11), a Los Angeles judge reversed his own previous decision and allowed Kerri Kasem the authority to have doctors end her father's infusions of water, food and medicine after his doctors concluded those measures would "at best prolong the dying process for him and will certainly add suffering to an already terribly uncomfortable dying process," according to CNN.
