Officials say a wave of drug dealers and addicts are traveling from Kentucky to visit Florida pain clinics.
Federal prosecutors said more than 24 people drove from Kentucky to Palm Beach County and Fort Lauderdale throughout 2005 and 2006 to pick up cases of prescription pain killers.
Eight have pleaded guilty to drug-trafficking charges. Several others are facing trial in Kentucky state courts for drug-related crimes.
Prosecutors said drugs prescribed by Florida doctors caused the deaths of five people in Kentucky. One man died from a fatal overdose during the 18 hour drive home.
