Casey Kasem

The mysterious, scandalous details surrounding the death four years ago of radio legend Casey Kasem will be explored this Saturday, Nov. 24, in an episode of “48 Hours” on CBS-TV. For the first time, his wife, Jean Kasem, reveals her version of her husband’s final days, while discussing allegations of murder in a lawsuit, and an ongoing family feud.

“The Mysterious Death of Casey Kasem” will air at 10pm, investigating his passing on Father’s Day, June 15, 2014, after which “the feud turned nuclear as both sides accused each other of hastening his death, as they battled over his enormous estate and his final resting place,” CBS says in a news release.

Kasem, of course, was heard by millions around the world as the host of the consummate music countdown show “American Top 40”—and as the voice of Shaggy in the cartoon classic “Scooby Doo.”

In “48 Hours,” Jean Kasem holds no punches: “They killed my husband,” she tells host Peter Van Sant. “They killed their father…” Counters Kerri Kasem, one of Kasem’s three adult children, “Jean killed my father. What she did led to his death.”

In 2014 Casey Kasem was dying of a Parkinson’s-like disease, CBS explains. At the time his estate was estimated to be worth between $80 million to $100 million. His family – Jean on one side and his adult children on the other – went to war over the money. Jean Kasem says her husband’s children, Kerri, Julie and Michael, were only after his money and that eventually her husband cut them off financially, according to CBS. “It was always all about the money,” she says. “We became the bank of Kasem – we were the personal ATM machine.”

She claims the children were furious and initiated a premeditated plan that led to their father’s death. Kerri Kasem and her siblings say it’s not true. “The only thing [Jean Kasem] ever wanted from my dad is money,” Kerri Kasem says. “That’s it.”

Van Sant and “48 Hours” explore the host’s life, death and legacy in “The Mysterious Death of Casey Kasem,” produced by Chuck Stevenson and Resa Matthews.

Kasem continues to be heard on-demand on iHeartRadio, which offers a dedicated 24/7 “American Top 40” channel; while SiriusXM airs shows from the 1970s on weekends.
