On December 13, Justice Authority Alberto López Rosas, during a radio interview with Carmen Aristegui , declared that one of the detainees -who is 19-years-old- had an AK-47, but they didn't know if the bullets matched the caliber that killed the two students. 
Mnamo Desemba 13, Mkuu wa Sheria Alberto López Rosas, wakati wa mahojiano ya redio Carmen Aristegui , alitangaza kuwa mmoja wa waliowekwa kizuizini - ambaye ana umri wa miaka 19 alikuwa na bunduki aina ya AK-47, lakini bado hawajajua kama risasi zinawiana na zile zilizowauwa wanafunzi wawili.
