The daughter of missing radio legend Casey Kasem plans to file a missing persons report, clearing the way for police and the FBI to get involved, her publicist said Tuesday.

Kerri Kasem, who was appointed as her father's temporary caretaker during a hearing Monday, will file the report "as soon as the paperwork for the conservatorship is done," according to a statement from Danny Deraney, her publicist.

Adult Protective Services, a court investigator and Kasem's family searched Tuesday for the 82-year-old "Top 40" host and radio personality, but they have not found him.

Casey Kasem is suffering from Lewy body disease, a form of dementia, according to his daughters. They told a judge during the hearing Monday that they don't know where he is being treated.

Judge Daniel S. Murphy ordered a court investigator Monday to find Kasem, after hearing conflicting information that he is either at a native American reservation in Washington or is out of the country, a court spokeswoman told NBC News.

Casey Kasem's children have complained for months that they've been barred from seeing their father. Kerry Kasem's lawyer told the judge the family believes Kasem is being treated in Washington state.
