One day after Michael Jackson's sudden death, speculation was already turning to what killed the 50-year-old "King of Pop" just weeks before a long-awaited series of comeback concerts.
A family attorney said on Friday he had been concerned that Jackson's use of prescription drugs for dancing-related injuries would eventually prove fatal and that the entertainer's inner circle had ignored his warnings.
Authorities scheduled an autopsy for Friday. But they cautioned it could take weeks to determine a cause of death, which will likely have to wait for the return of toxicology tests. Those tests will determine if Jackson had any drugs, alcohol or prescription medications in his system.
