Michael Jackson’s personal physician, Dr. Conrad Murray, 57, was charged today with involuntary manslaughter for allegedly giving Jackson lethal levels of the hospital-strength anesthetic propofol while treating him for insomnia, according to People. A court hearing is set for this afternoon, and Murray, who has denied any wrongdoing, is expected to voluntarily turn himself in, enter a not-guilty plea, and post bail. The L.A. County D.A.’s office filed the charge, which was based on the county coroner’s finding that found an overdose of the anesthetic in Jackson before his June 25 death. The penalty against Murray can range from probation to four years in prison, a less severe sentence than if prosecutors had charged him with second-degree murder.
