The news was confirmed by Casey's Kasem's agent, Don Pitts. He says there will be a memorial service on Friday. Casey Kasem had been hospitalized in Washington state for two weeks.
Kasem's children -- Kerri, Mike and Julie -- wrote in a statement, "Early this Father's Day morning, our dad Casey Kasem passed away surrounded by family and friends. Even though we know he is in a better place and no longer suffering, we are heartbroken ... The world will miss Casey Kasem, an incredible talent and humanitarian; we will miss our Dad."
Kasem was born in Detroit and started his disc jockey career in Flint before becoming an announcer on Armed Forces Radio Korea Network in 1952. He then worked at radio stations in California, Ohio and New York before launching "American Top 40" in 1970. He was the host until 1988, and hosted again from 1998 to 2004. He also hosted for ten years on "Casey's Top 40."
Kasem was married twice and had four children. He was the voice of many TV characters, including Shaggy on "Scooby-Doo" as well as the voice on many commercials. He supported animal rights and was vegan. He supported environmental causes, as well as political organizations.
His health declined and last year his daughter Kerri said he was suffering from dementia. His three oldest children and brother launched a claim that his current wife Jean was not letting them see their father. A court denied a petition launched to let his daughter take care of him in October 2013, but last month, Kerri was granted conservatorship amid a battle with Kasem's second wife.
Casey Kasem was hospitalized after an argument between Jean and Kerri. Last week, a Los Angeles County judge gave daughter Kerri Kasem the authority to have doctors end his infusions of water, food and medicine.
