A pilot killed when his marijuana-laden ultralight plane crashed in a field in San Luis has been identified as a Mexican man.

Field workers found the plane in a lettuce field early Monday. San Luis police Lt. Blanca Silva identified him Wednesday as 34-year-old Juan Gabriel Hernandez Torres of San Luis, Mexico.

The ultralight apparently crashed sometime during the night and was found when fieldworkers arrived for work. Silva says several bundles of marijuana weighing more than 140 pounds was strapped to the aircraft.

The crash site is about 3/4 of a mile north of the border with Mexico.

The U.S. Border Patrol says it is the second time in recent weeks a small motorized glider was used in a smuggling attempt.
