Joe Jackson suspects foul play in the recent death of Michael Jackson, the most famous of his six sons.

Joe, 80, says he was shocked when he learned the pop icon had been rushed to the hospital on June 25.

“I just couldn’t believe what was happening to Michael,” he said.

“I do believe it was foul play,” the father of the late singer says in a special edition of Primetime: Family Secrets — The Jackson Family: Life After Michael, set to air this Tuesday, July 14.

“I do believe that. Yes.”
