A dispute at a Roswell mobile-home park turned fatal on September 4, 2025, when 21-year-old Colton Porter was shot in the upper chest after confronting a man who had broken a window at his home. Porter, a White male, was taken to a local hospital and pronounced dead on arrival.

Police say 40-year-old Marcos Prieto arrived at Porter’s residence, broke a window, and called for Porter to come outside. Porter armed himself with a knife and went out to confront Prieto; witnesses heard a single gunshot moments later and reported a blue pickup truck speeding away. Officers located a matching truck at a nearby McDonald’s and found Prieto as the sole occupant. He attempted to flee but was detained.

Officers found a handgun believed to be the gun used in the shooting and fentanyl pills during a search of Prieto and the vehicle. Prieto was booked into the Chaves County Detention Center and charged with first-degree murder, possession of a controlled substance, and resisting, evading, or obstructing an officer.

Did anyone in the Roswell area witness the confrontation or the truck leaving the scene?
