On the early morning of July 10, 2016, 24-year-old Marvin Lopez was shot and killed outside a party on the 4200 block of West 5615 South in Kearns, Utah. Witnesses say a dark-colored sedan returned to the house; a passenger asked for a specific person and claimed to be looking for a gang member. Marvin stepped forward and identified himself as from that gang. A rear-seat passenger then produced a handgun and opened fire. Marvin was struck three times, twice in the chest and once in the left leg, and was pronounced dead after being taken to a hospital.

The case remained cold for years until ballistic testing in 2022 linked .380 shell casings from Marvin’s scene to a shooting nine days earlier in West Valley City. Investigators focused on Jimmy Alexis Lopez, who was 18 at the time of the killing and not related to Marvin. Prosecutors say further evidence from a later arrest included phone data showing gang activity and searches about Marvin’s homicide and gun ballistics, and a witness identified Jimmy Lopez in a photo lineup in May 2023. In February 2025 Jimmy Alexis Lopez, then 27, was arrested on murder and multiple counts of felony discharge of a firearm. Authorities say they want to speak with three other people who were in the car that night.

Did anyone at the party or in that neighborhood notice the dark-colored sedan or the occupants that morning?
