Mexican drug cartels offering bounty to stop American Indian Shadow Wolves

The Shadow Wolves, a special American Indian tracker unit, combine traditional tracking skills with modern police techniques to thwart drug and human smugglers. They work with U.S. Immigration and Customs Enforcement.

Mexican drug cartels have now put a bounty of $500,000 on the Shadow Wolves. The cartels also put a price on the members of the Shadow Wolves' families. The cartels say they will pay $50,000 for the death of an immediate family member.

The 18 member Shadow Wolves unit patrols the Tohono O'odham Nation on the U.S-Mexico border, and are responsible for some of the largest seizures of drugs in the U.S. More than 1,500 immigrants use the Tohono O'odham Reservation to illegally enter the U.S. every day.

Within three months of being assigned to ICE in October, the Shadow Wolves found 3.5 tons of marijuana on the northern part of the Tohono O'odham Nation. Since then, they have seized a total of 22,723 pounds of marijuana.
