Where is Casey Kasem?
The daughter of the legendary radio host says her father disappeared May 7, a day after she visited him in a care facility. Kerri Kasem is now preparing to file a missing persons report, her rep tells PEOPLE.
The report will allow the FBI and local police agencies to get involved in the search for Kasem, 82, who suffers from advanced Parkinson's disease and can no longer speak. A judge also has ordered an investigation into Kasem's whereabouts.
Kerri Kasem alleges that her stepmother, Casey's wife Jean Kasem, recently moved Casey, possibly to an Indian reservation in Canada or Washington State.
"We don't know where he is. Nobody knows," says Kerri's rep, Danny Deraney.
Jean's attorney said at a hearing
Monday that the former American Top 40
host had been moved out of the country, but didn't know exactly where.
The judge appointed Kerri Kasem her father's temporary caretaker, the latest move in an ugly dispute
between the host's children and Jean.
