MONTERREY, Nuevo Leon — Authorities are on alert after four police officers from the state of San Luis Potosi were injured by an improvised explosive device (IED).
While San Luis Potosi does not border the U.S., it is monitored by federal agencies in Mexico since it is one of the areas that drug cartels have been fighting over and spreading a wave of terror, just like in Nuevo Leon and Tamaulipas.
A ballistics expert that works with Mexico’s federal government that asked to remain anonymous spoke with Breitbart Texas about the ongoing strengthening of protocols for investigating suspicious crime scenes as a result of the new tactic.
In a case that went unnoticed by Mexican or international news outlets, suspected members of the Cartel Del Noreste (CDN) left an IED for state investigators to trigger at a crime scene. The explosive was hidden in an ice chest with a narco message. At the time of the attack, it was reported there were human remains inside a Grand Cherokee SUV.
