Mauricio had to call in a favor for a disposable van, and owe a favor to some 'high-end' outside help. The van was large and hollow, and carried the guys, each one having a considerably bigger or better gun with them. Mauricio himself went and picked up a Colt CM901 from one of his stashes. The help he got brought their own guns, which were basically powerful shotgun, twin UZIs, and an assault rifle customized with a grenade launcher. The weapons would be the only things normal about them. If someone were to look at everyone in the van, then they would notice that three people stand out like a halloween-themed house on Valentines Day. These three were from an organization called "Asesinos Mexicano Espía", and they were very good at what they do, if a little eccentric.
So'rolla was easily the most normal-looking out of the three, wearing white pants and the Mexican version of a Hawaiian shirt. La Luna Loco was...well, let's just say that Bane's not the only one with a luchadore theme going on. Madame Mariel was a mix of the two. She didn't wear normal clothing, but she definitely didn't take it to the extreme like her masked cohort. These three were the best at what they do, and that would be assassination. And they would be the edge that helps them in this.
As soon as they pulled over near the warehouse that the Calculator had tracked, the three went to work, disappearing as soon as they were out of the van. Mauricio himself wasn't surprised, and called the Calculator to thank him for his services, and transfer the payment. As for the others, he told them to get out and get ready, because things were about to get hot.
