The network was integrated by nine people who were in charge of transporting and selling parts of high-caliber firearms and for the exclusive use of the armed forces, through parcels on bus or human couriers. Preventive detention orders were issued for all the defendants.
The alleged criminals offered and sold war weapons such as rifles and M-60 machine guns. To hide these guns, they were packed in large items that did not arouse suspicion. In some cases individuals used plastic table legs to hide large cylinders and components of long-range armament, while the smaller parts were carried by women in their clothes.
The investigation established the possible participation of the defendants in the trafficking of firearms and criminal conspiracy through legal wiretappings of their conversations which revealed the purchase, transport, recruitment of human couriers, packaging of the weapons and, occasionally, the instructions to assemble the rifles along with the characteristics of each weapon.
