On Sunday afternoon, November 26, 2017, ranch hands and deputies followed smoke from a burning SUV off Burlington Trail Road to a reservoir on the Wyoming Hereford Ranch east of Cheyenne. In the water they found 19-year-old Justin Randall Robinson floating face down. The Laramie County coroner and sheriff’s office ruled the death a homicide, a single gunshot to the head; one report described the bullet entering behind the right ear and exiting near the left ear.

Robinson had been born at Fort Hood, Texas, and raised in Cheyenne, where he completed the Wyoming Cowboy Challenge program in 2016. Obituaries remembered him as a young man who loved music, bonfires, fishing, and camping. Investigators found a burned vehicle, a scene with blood, and a stolen .40-caliber handgun; they described an armed suspect as dangerous. Charges soon followed: a 17-year-old was arrested on accessory and arson allegations, and deputies sought 21-year-old Armando Raul Ramirez-Serna for questioning. Ramirez-Serna was arrested in Kimball, Nebraska, and later admitted in a federal plea that he shot Robinson during a robbery, took marijuana and cash, dumped the body in the reservoir, and set the SUV on fire. He received a 40-year prison sentence in February 2019.

Who knew Justin or was in that area on November 26, 2017, and might have information about the events that afternoon?
