Officials in Arizona say an increase in smuggling violence has led to a stronger warning to visitors about drug and immigrant traffickers passing through public lands
about 80 miles south of Phoenix.
The Sonoran Desert National Monument and three other federal lands in Arizona already have signs warning visitors that they may encounter smugglers. But 11 new signs have been erected and two more were planned at the Sonoran Desert National Monument at Casa Grande.
The signs tell visitors about speeding smuggling vehicles and instruct them to walk away if they see something suspicious and avoid abandoned vehicles and backpacks because they might contain drugs stashed there by smugglers.
