Mexico City The four tons of cocaine found aboard a U.S.-registered business jet that crashed in Mexico's Yucatan Peninsula on Monday belonged to Joaquin "El Chapo" Guzman, this country's most notorious drug trafficker, Mexican authorities said Friday.
The business jet that was transporting the dope to Mexico from Colombia was purchased just a week before the crash by a U.S. pilot with a history of legal and financial problems in Florida, interviews and official records indicate, but whether the pilot still owned the plane at the time of its crash is unknown.
The complex sale of the Gulfstream II jet and its end in the Mexican jungle highlight the increasingly complicated illicit drug trade. A recent report by the U.S. Government Accountability Office said the trade generates as much as $23 billion a year for Mexico-based drug cartels.
U.S. authorities say as much as 90 percent of the cocaine sold in the U.S. is shipped through.
