The verdict marked the latest chapter in one of pop culture'smost shocking tragedies - the 2009 drug-overdose death of the Kingof Pop at age 50 as he was about to mount a series of heavilypromoted concerts in London that he hoped would turn his careeraround after a slide prompted by child-molestation allegations andyears of bizarre behavior.

A shriek broke the silence in the packed courtroom when thejury's decision was read, and the crowd outside the courthouseerupted in cheers. Jubilant Jackson fans sang "Beat It" and heldsigns that read "Guilty" and "Killer." Drivers honked theirhorns.

Members of Jackson's family wept, and his mother, KatherineJackson, said, "I feel better now." His sister La Toya said shewas overjoyed and added: "Michael was looking over us."

Members of the jury were escorted from the building and notavailable for comment.

Defense attorney Ed Chernoff said later in the day the verdictwas a disappointment and would be appealed. Asked how Murray tookthe verdict, Chernoff said, "he's a pretty strong guy."

Regarding Murray's future, he said, "the keys to his handcuffsbelong to the judge. We certainly would like to do anything we canto keep him from going to prison."
