Detectives Probing Jackson's Rx, MDs

Los Angeles - The Los Angeles police chief says detectives investigating the death of Michael Jackson are looking at his prescription drug history and trying to talk with his numerous former doctors.

Chief William Bratton tells CNN that police are waiting for the coroner's report before ruling out any possibilities in their "comprehensive and far-reaching" investigation into the sudden death of the 50-year-old pop star two weeks ago.

The coroner's report will determine the cause of death and hinges on time-consuming toxicology tests, but detectives are already gathering evidence.

Bratton says the Drug Enforcement Agency and the state attorney general's office, which keeps a database of prescription drugs, are assisting investigators.
