Michael Jackson’s doctor was convicted Monday of involuntary manslaughter after a trial that accused him of being Jackson’s caregiver who administered a lethal dose of a powerful anesthetic that killed the pop star. As the verdict against Dr. Conrad Murray was read, members of Jackson’s family wept quietly, and his mother, Katherine Jackson, later told The Associated Press, “I feel better now.” Sister La Toya Jackson told the AP she was overjoyed. Murray sat stone-faced during the verdict and was handcuffed and taken into custody without bail until sentencing on November 29. He appeared calm as officials led him out of the courtroom. A shriek broke the eerie silence in the packed courtroom when the verdict was read, and the crowd erupted outside the courthouse. The jury deliberated less than nine hours. Murray, 58, faces a sentence of up to four years in prison. He could also lose his medical license.
