In October 2013, Kerri Kasem announced her father had Parkinson's disease, diagnosed in 2007. However, a few months later, she said he had Lewy body dementia, which is hard to differentiate from Parkinson's. His condition left him unable to speak during his final months.
As Kasem's health worsened in 2013, his wife Jean prevented any contact with him, particularly with his children from his first marriage. On October 1, the children protested in front of the Kasem home. Some of Kasem's friends and colleagues, and his brother Mouner, joined the protest. The older Kasem children sought conservatorship over their father's care. The court denied their petition in November.
Jean removed Kasem from his Santa Monica, California nursing home on May 7, 2014. On May 12, Kerri Kasem was granted temporary conservatorship over her father, despite her stepmother's objection. The court ordered an investigation into Casey Kasem's whereabouts after his wife's attorney told the court that Casey was "no longer in the United States". He was found soon afterward in Washington state.
On June 6, 2014, Kasem was reported to be in critical but stable condition in a hospital in Washington state, receiving antibiotics for bedsores and treatment for high blood pressure. It was revealed he had been bedridden for some time.[58] A judge ordered separate visitation times for Kasem's wife and his children from his first marriage. Judge Daniel S. Murphy ruled that Kasem had to be hydrated, fed, and medicated as a court-appointed lawyer reported on his health status. Jean Kasem claimed he had been given no food, water, or medication the previous weekend. Kerri Kasem's lawyer stated that she had him removed from artificial food and water on the orders of a doctor and in accordance with a directive her father signed in 2007 saying he would not want to be kept alive if it "would result in a mere biological existence, devoid of cognitive function, with no reasonable hope for normal functioning." Murphy reversed his order the following Monday after it became known that Kasem's body was no longer responding to the artificial nutrition, allowing the family to place Kasem on "end-of-life" measures over the objections of Jean Kasem.
On June 15, 2014, Kasem died at St. Anthony's Hospital in Gig Harbor, Washington at the age of 82. The immediate cause of death was reported as sepsis caused by ulcerated bedsore. His body was handed over to his widow. Reportedly, Kasem wanted to be buried at Forest Lawn Memorial Park in Glendale.
By July 19, a judge had granted Kerri Kasem a temporary restraining order to prevent Jean Kasem from cremating the body in order to allow an autopsy to be performed. However, when Kerri Kasem went to give a copy of the order to the funeral home, she was informed that the body had been moved in the direction of Jean Kasem. Kasem's wife had the body moved to a funeral home in Montreal on July 14, 2014. On August 14, it was reported in the Norwegian newspaper Verdens Gang that Kasem was going to be buried in Oslo.
Jean Kasem had him interred at Oslo Western Civil Cemetery on December 16, 2014, more than six months after his death.
In November 2015, three of Kasem's children and his brother sued his widow for wrongful death. The lawsuit charges Jean Kasem with elder abuse and inflicting emotional distress on the children by restricting access before his death. A 2018 police investigation initiated by a private investigator working for Jean found that he had received appropriate medical care while in Washington and that there was no evidence pointing to homicide. The suits were settled in 2019.
Honors
In 1981, Kasem was granted a star on the Hollywood Walk of Fame. He was inducted into the National Association of Broadcasters Hall of Fame radio division in 1985, and the National Radio Hall of Fame in 1992. Five years later, he received the Radio Hall of Fame's first Lifetime Achievement Award. In 2003, Kasem was given the Radio Icon award at the Radio Music Awards.
