After his children complained about not being able to see their father, a Los Angeles judge has ordered an investigation into the whereabouts of radio legend Casey Kasem.

His children claim that Kasem's wife, Jean, has moved him out of Los Angeles without their knowledge and now refuses to tell them where their father is.

The 82-year-old Kasem suffers from advanced Parkinson's disease and can no longer speak. His daughter, Kerri, is seeking a temporary conservatorship of her father and on Monday was appointed her father's temporary care-giver, The Los Angeles Times reported.
