A teenager with a gunshot wound and signs of torture was found hanging over a motorway with a dead body strung up next to him.
The body of a third man was found below the bridge on the busy road in what appears to have been a hit by a drug cartel.
Witnesses told police that a group of gunmen got out of a vehicle and threw the men over the side of a bridge at around 10am, stopping traffic along one of the busiest routes in Mexico’s third largest city, Monterrey.
