Mexican authorities believe that a stolen truck outfitted with a cannon and parked near the U.S.-Mexico border was used to launch items into Douglas, Arizona.
Federal police found the van parked in a street in Agua Prieta, Mexico, which borders with Douglas, last week. The van had been reported stolen out of Hermosillo over the summer.
Photos provided by Mexican authorities show a black van with a giant cannon coming out of it.
Drug smugglers have used similar methods in the past, including using catapults to literally send drugs flying over the border. Douglas border residents have found bales of marijuana in their backyards in the past.
