Authorities say 33 cans of marijuana were spotted Friday in a field near where the Colorado River crosses the U.S.-Mexico border. They believe the cans were launched about 500 feet into the U.S. using a pneumatic-powered cannon.
After searching the area, agents recovered a carbon dioxide tank. Mexican authorities were also notified and searched their side of the border.
The 85 pounds of marijuana found in the cans had an estimated value of $42,500.
Authorities say Border Patrol agents in the Yuma sector near the Arizona-California border are adapting and shifting resources as smugglers come up with new ways of transporting their contraband.
