Gilberto Marron was 24 when he was found dead of gunshot wounds on October 9, 2019, in Greeley, Colorado. His body was discovered in the backseat of a car parked outside the 16th Street Gym; the vehicle belonged to the wife of the man later identified as the primary suspect. The Greeley Police Department named 42-year-old Jamie Gonzalez-Quezada as the suspect.

Gonzalez-Quezada fled the scene initially but turned himself in at a Greeley police station a few hours after the shooting and was arrested. He was charged with second-degree murder and reckless endangerment. The case went to trial, and a jury found Gonzalez-Quezada guilty in May 2021; in July 2021 a judge sentenced him to 48 years in prison.

Does anyone have information about Marron’s activities that day or knew him and can help fill in gaps about what led to this confrontation?
