A judge in California ordered an investigation into the whereabouts of radio and entertainment legend Casey Kasem after family members said he may have been taken to a reservation in Washington.

Kasem's children say they haven't seen their 82-year-old father since he was removed from a private care facility sometime last week. The believe he could have been moved to the unidentified reservation as part of a plan to take him out of the country.

"I believe my father's wife fled the country (or possibly went to an Indian Reservation) with my Dad because she knew I would win in court today," daughter Kerri Kasem said on Facebook after the judge ordered the investigation.

Kasem suffers from Parkinson's disease, can no longer speak and is fed through a tube, The New York Daily News reported.
