How did the alleged involvement of Katherine Andrea Martínez Martínez and the weapon's transportation contribute to the investigation?

The investigation implicates El Costeño in contracting the underage shooter and providing the weapon, a Glock 9mm pistol. Evidence includes security footage showing El Costeño with the minor before the attack and testimonies from co-conspirators like Katherine Andrea Martínez Martínez, who transported the weapon. Allegedly, El Costeño received orders from another criminal leader, El Churco, based in Ecuador.
