Some of the narcotics that Los Angeles police found in Michael Jackson's house were obtained by the singer outside of the United States, RadarOnline.com has learned.
"The investigation is going to go international," a source close to the situation told RadarOnline.com exclusively. The DEA and the Attorney General are now involved in the case.
But it is going to be very difficult to track down the drugs Jackson obtained outside of the U.S., the source told RadarOnline.com. "The investigation is growing."
U.S. law enforcement will ask for help from foreign law enforcement, the source told RadarOnline.com. As RadarOnline.com previously reported police found a large quantity of drugs inside Jackson's house, including the powerful sedative Diprivan.
