MJacksonHiding061609x.jpg A law enforcement official in Washington D.C. has confirmed that the Drug Enforcement Administration is now joining the investigation of Michael Jackson's death.

According to The Associated Press, the official says the Los Angeles Police Department asked the DEA to step in because of their knowledge and resources of illicit drug manufacturers known as "pill mills."

The federal agency would also play a role in looking at Jackson's doctors and whether they were registered with the DEA to prescribe drugs. Also, federal investigators will try to determine the sources of the drugs doctors prescribed for Jackson to see whether or not there is a trafficking pattern.

Sounds like some pretty serious stuff...should be interesting to see what they'll find!
