Where is Casey Kasem? Twitter Explodes with Theories Linking Jay Z to Former Radio Host

Legendary radio host Casey Kasem is missing, and a judge on Monday ordered an investigation to find the 82-year-old's whereabouts.

The "Top 40" radio legend has advanced Parkinson's disease and his adult children believe their stepmom Jean Kasem has taken their father to an Indian reservation in Washington.

"We're going to find him, take care of him and love him," daughter Kerri said in an exclusive interview with the New York Daily News. "He's going to be with family, not stuck in some unfamiliar place where he's dying alone."

"I'm just praying to God she hasn't hurt him. He's very ill and fragile right now. He would need an airplane with special medical services," the daughter added.

Casey can no longer speak and has been in various treatment facilities chosen by Jean. On Jean's motive behind moving Casey out of Los Angeles, Kerri said that she can only speculate, as they have been estranged for years.

"In my opinion, this is something only someone with severe mental illness would do," Kerri said.

On Monday, Kerri was appointed temporary caretaker of her father, and she will now have access to his medical records that were previously sealed.

Meanwhile, Twitter has been abuzz with theories on what could have happened to Casey.
