Multiple doctors, including Dr. Conrad Murray, are suspected of prescribing drugs to Michael Jackson under fake names.
Drugs were reportedly prescribed to aliases Omar Arnold, Joseph Scruz and Bill Bray.
Murray was in Jackson's L.A. home when the superstar collapsed, and has reportedly left the west coast. The cardiologist is said to be hiding out in his hometown of Houston.
Sources tell "Extra" that Murray is being guarded by the same super-tight security team that once protected the King of Pop.
