DEA cracks down on Mexican cartel and Louisville gang connection.

The DEA's yearlong "Operation Last Mile" targeting the links between Mexican drug cartels and local street gangs and drug dealers resulted in massive drug busts in Louisville and other cities. The Jalisco and Sinaloa cartels smuggle fentanyl and methamphetamine into the United States and then distribute those drugs to local street gangs and individual drug dealers. The Louisville Field Division's investigations resulted in 137 arrests and seizures of 1,762,240 deadly doses of fentanyl, 544 pounds of methamphetamine, 621 guns, and $4,336,891 in assets. Many acts of violence in Louisville can be traced to the cartels' local affiliates.
