Michael Jackson dies at age 50

'King of Pop' dies in LA

Jackson was preparing for what was to be his greatest comeback: He was scheduled for an unprecedented 50 shows at a London arena, with the first set for July 13. He was in rehearsals in Los Angeles for the concert, an extravaganza that was to capture the classic Jackson magic: showstopping dance moves, elaborate staging and throbbing dance beats.

Singer Dionne Warwick said: "Michael was a friend and undoubtedly one of the world's greatest entertainers that I fortunately had the pleasure of working with. ... We have lost an icon in our industry."

Jackson's death brought a tragic end to a long, bizarre, sometimes farcical decline from his peak in the 1980s, when he was popular music's premier all-around performer, a uniter of black and white music who shattered the race barrier on MTV, dominated the charts and dazzled even more on stage.

Michael Jackson, the sensationally gifted child star who rose to become the "King of Pop" and the biggest celebrity in the world only to fall from his throne in a freakish series of scandals, died Thursday. He was 50. Jackson died at UCLA Medical Center in Los Angeles. Ed Winter, the assistant chief coroner for Los Angeles County, confirmed his office had been notified of the death and would handle the investigation.
