Marlon Porfirio Osorio-Rivera, 51, a Latino man, was found fatally shot just after sunrise on Saturday, August 13, 2016, in a North Las Vegas neighborhood near Stocker Street and East Tonopah Avenue. Officers responding around 6 a.m. discovered him on the ground with a gunshot wound; medical personnel pronounced him dead at the scene. The coroner later identified him publicly, confirming his age and name, as detectives canvassed the residential blocks not far from Lake Mead Boulevard where
neighbors had reported hearing gunfire in the quiet of early morning.
Investigators said the circumstances pointed to a possible robbery during the moments before the shooting. Accounts from local reporting described Osorio-Rivera as a hardworking family man—originally from Guatemala—whose life revolved around his faith and his close-knit family. Loved ones pleaded for answers while detectives sought tips from anyone who might have seen a person or vehicle fleeing in those early hours.
Police stated that no assailant was immediately identified, and news updates in the days that followed did not announce an arrest. Contemporary wire reports reiterated that detectives were treating the killing as a robbery-related slaying and appealed for the public’s help. Public homicide trackers and victim registries continued to list the case without a named suspect, underscoring how quickly the trail cooled after that August morning.
