LOS ANGELES (AP) — The attorney for Dr. Conrad Murray says he will appeal his conviction for involuntary manslaughter in the death of pop star Michael Jackson.Asked how Murray took the verdict, defense attorney Ed Chernoff said, "he's a pretty strong guy."Dr. Conrad Murray sat stone-faced, his chin held high, as he heard the verdict that could send him to prison for up to four years and cost him his license to practice medicine. He was handcuffed and immediately led off to jail without bail to await sentencing Nov. 29.A seven-man, five-woman jury convicted Murray of being substantially responsible for Jackson's June 2009 death on Monday after less than nine hours of deliberations.Jackson's family wept, and his mother, Katherine Jackson, said, "I feel better now."Members of the jury were escorted from the building and not available for comment.
