The Kasem Kids Fight for Their Father

Hoping that by taking their situation to national headlines they could make progress at home, Casey Kasem's children are speaking out about their father's battle with Parkinson’s disease.

The former “Scooby-Doo” voice actor’s three children, Julie, Kerri and Mike, from his previous marriage to Linda Myers, say they have not been able to see their father in three months because their stepmom and Casey's wife of over 30 years, Jean Kasem, is prohibiting them from visiting.

"Unfortunately the disease may be killing his body but it doesn't need to kill his spirit and his soul," Casey's daughter Julie said on the Today show this morning. Jean reportedly refuses to return their messages.

"He can't really speak, but he knows we're there," Kerri Kasem said to ABC7. "And last time we saw him, he could shuffle a little bit. He had a hard, very hard, time walking. He was just deteriorating due to Parkinson's disease."
