(BREITBART) — GOMEZ FARIAS, Tamaulipas — Human rights activists searching for cartel victims found an extermination field used by Los Zetas to bury and incinerate at least 500 near a UNESCO-protected ecological biosphere.
The extermination field was found in the southeastern part of Tamaulipas in the rural community of Alfredo Bonfil. The area is close to El Cielo Biosphere, a protected ecological site known as Mexico’s northernmost tropical forest and cloud forest region.
Breitbart Texas was able to confirm through Mexican court documents that Los Zetas members confessed to operating multiple incineration sites throughout the border state.
