Drug runners have apparently turned to drones to shuttle meth across the border with Mexico.

The Tijuana Public Safety Secretariat says a drone packed with methamphetamine “crashed into a parking lot in Mexico close to the California border,” the Chicago Tribune reports.

It was found at about 10 p.m. local time and was carrying about 6 pounds of the drug.

The secretariat theorizes the drone crashed because it was overloaded.

They say the runners were using a Spreading Wings S900 model, which has six propellers.

Authorities refer to the drones as “blind mules.”

CBS reports catapults, ultralight aircraft and tunnels have also been used in the past.

Estimates indicate the six pounds of meth would have a street value of about $260,000.
