Surenos is a criminal gang in Butcher Bay Correctional Facility. It is lead by Cuellas. Once a man named Cipriano, who used to traffic drugs for Surenos, double-booked with Zolus. Surenos put a hit on Cipriano, and guy named Padilla took it. He however failed and it's unknown if someone else took the contract. Surenos had gotten a list of snitches from a guard, but the list went missing. Cuellas told Riddick that if he wanted to be in good graces with Surenos he'd keep an eye open for the list.
