Rio de Janeiro, Brazil—Bad day for a pair of drug traffickers in Brazil: their truck loaded with marijuana and a car escorting it plunged off a mountain road near Rio de Janeiro, spilling a load of 1.3 tons of pot.

The driver of the truck, which crashed on Saturday apparently because due to high speed, fled before police could arrive, police said.

When they did get to the scene, the driver of the escort car, who was slightly injured, was arrested, hospitalized and charged with drug trafficking.

Police said he "can't remember a thing."
