The wife of U.S. Tv and radio star Casey Kasem has been ordered to appear in a Washington court on Friday (30May14) to answer questions about the ailing star's care.

Jean Kasem has been embroiled in a battle with stepdaughter Kerri Kasem over the care of the 82-year-old broadcasting legend, who suffers from Parkinson's disease, and now the broadcaster's daughter wants a face-off in court.

Earlier this month (May14), Kerri was appointed her father's official caretaker just days after she filed a missing persons report amid fears her dad had been "kidnapped" by his wife.
