2 plead guilty in California to smuggling nearly 30 pounds of heroin from Mexico by drone

1-- Two California men pleaded guilty to using drones to smuggle nearly 30 pounds (13.61 kilograms) of heroin from Mexico to the United States, authorities said Wednesday.
2It was the first drug seizure involving a drone along California's border with Mexico, said Lauren Mack, spokeswoman for U.S. Immigration and Customs Enforcement in San Diego.
3She was unaware of any other drone-related seizure on the 1,954-mile divide between the two countries.
4Jonathan Elias, 18, and Brayan Valle, 19, admitted in federal court Tuesday that they drove to a field in Calexico, California, in April to pick up a bag with 28.6 pounds of heroin that was sent across the border by drone.
5Elias took over control of the drone from an operator in Mexico after the aircraft crossed the border, Mack said.
6In a plea agreement, Valle acknowledged placing the drugs in the trunk.
7"With border security tight, drug traffickers have thought of every conceivable method to move their drugs over, under and through the border," said Laura Duffy, U.S. attorney for the Southern District of California.
8"We have found their tunnels, their Cessnas, their jet skis, their pangas, and now we have found their drones."
9The discovery comes about four years after authorities began discovering ultralight aircraft making lightning-quick runs across the border in California's Imperial Valley to drop bundles of marijuana, a tactic that has since become more common on other stretches of border.
