Dr. Conrad Murray, the Houston physician that was with Michael Jackson when the musician died of an overdose last summer, will be arraigned in Los Angeles on Friday on a charge manslaughter in connection with the King of Pop’s death, a source with knowledge of the investigation tells The Associated Press.
