TIJUANA, Mexico -- A smuggler's drone flying from Mexico crash-landed just south of the U.S. border city of San Ysidro, California, in a failed drug delivery this week, the Tijuana Municipal Police said.
The incident showed that smugglers aren't just going underground any more, using tunnels beneath the U.S.-Mexico border to transport drugs and migrants.
Now the smugglers are trying to do business by air, too, in unmanned aerial vehicles.
The drone was loaded with more than 6 pounds of the synthetic drug crystal meth, Tijuana police said.
The drone crashed Tuesday night in a supermarket parking lot in Tijuana.
Apparently the smugglers became too greedy, authorities said.
The silver and black, six-propeller Spreading Wings S900 model was not able to withstand the weight of the load and crashed, police said.
"In San Diego, the street value, at last account, for a 6-pound load would be about $48,000," DEA Special Agent Matt Barden said. "Once you get it across the border, that stuff's like gold."
This wasn't the first time a drone was used in a smuggling attempt from Mexico, according to drug war analysts, U.S. officials and local Mexican police.
But the incident amplified concerns about border security and officers' safety.
"I would hate to belittle 6 pounds of meth," Barden said. "That's like saying 6 pounds of heroin isn't bad ... but I think the big thing to look at is the fact that the cartels or drug traffickers from Mexico are using drones in their playbook.
"My greater fear, being an agent, is what a drone means to officer safety. That to me, personally, being a tactical officer, that's my concern," he added.
Drones are emerging as the latest technological gadget used by cartels and smugglers in trying to outfox border authorities.
The crashed drone was a prototype that used a global positioning system, or GPS, to send it to a particular destination, Tijuana police said on the department's Facebook page.
"The cartels have been using drones for surveillance. Transporting drugs is a bit more complicated," said Sylvia Longmire, a leading drug war analyst. "This is further evidence that the cartels have unlimited funds and creativity."
As to why smugglers would attempt to transfer what in the grand scheme is "not that much," both Longmire and Barden were in agreement.
"My guess ... it might be a personal load," Longmire said.
"When you look at cartels, their goal is to flood the U.S. with as much drugs as they possibly can," Barden said. "It also could have been a test run for something bigger."
