From WPEC-TV, West Palm Beach:
Police in a Mexican border city said on Wednesday that a drone packed with 6 pounds of crystal meth crashed into a supermarket parking lot.
Tijuana police director Patricia Sida Wilkes said authorities were alerted after the drone fell on Tuesday night near the San Ysidro crossing at Mexico's border with California.
Six packets of the drug, weighing more than six pounds (2.7 kilograms), were taped to the six-propeller remote-controlled aircraft.
Authorities are investigating where the flight originated and who was controlling it.
It's not the first time drones have been used for smuggling drugs across the border.
Other innovative efforts have included catapults, ultralight aircraft and tunnels.
