Mexico has caught one of the supposed masterminds behind the apparent massacre of 43 student teachers last year, a police source said on Thursday, potentially raising hopes more will come to light in an incident still shrouded in mystery.
Federal police caught Gildardo Lopez, alias "El Gil," on Wednesday in the tourist town of Taxco, in the southwestern state of Guerrero, the source added, declining to be named given sensitivities around the case.
Prosecutors identify Lopez as a senior member of the Guerreros Unidos drug cartel and say he gave the order to incinerate the student teachers on the night of Sept. 26 last year near the town of Iguala, Guerrero.
