A bombshell ENQUIRER investigation has solved the mystery of John F. Kennedy Jr.'s deadly plane crash – a terrible drug secret triggered the accident.

John's wife Carolyn Bessette was a heavy user of cocaine and the powerful party drug Ecstasy – and her desperate last-minute search for drugs resulted in the tragedy that rocked America four years ago this month.

For the first time, a close friend of Carolyn has come forward to reveal how the blonde beauty spun out of control on drugs.
