The soldiers who walked into what looked like a tomato field in the desert near El Rosario, Baja California, on 12 July 2011 found about 120 hectares of marijuana instead.[1]The plot covered nearly 300 acres more than 150 miles south of Tijuana, and the army presented it as the largest marijuana plantation ever detected in Mexico.[1][2]
About 100 laborers were eating dinner when the patrol of some 30 soldiers arrived, and they fled into the hills.[1]The military captured two people in the field and detained another 56 at checkpoints set up around the area.[1]Brigadier General Alfonso Duarte Mugica, who oversaw the operation, said the crop could have yielded about 120 tons of marijuana worth about $160 million, and the defense ministry attributed the plantation to Joaquin Guzman and the Sinaloa cartel.[1][2]
Some 200 soldiers began burning the plants, work the authorities said could take a month, and boxes of highly toxic fertilizer were found at the site.[1]President Felipe Calderon congratulated the defense ministry, calling the find a big blow to organized crime.[1]
Case data
Every number and detail the sources state, with the sources that state it.
No plant count was published; 120 tons is the army's estimated yield, not a weighed seizure.
The army's claim that this was the largest plantation ever detected in Mexico was disputed in contemporary coverage, which cited an expert pointing to the bigger 1984 El Bufalo find.
