Chandler Michael Cooper, 22, was found dead on February 11, 2016, by hikers near a desolate trail by the Saltair pavilion in Magna, Utah. His body was located a few hundred yards from the intersection of the North Temple Frontage Road and 11500 West. Cooper, a resident of the Holladay-Millcreek area, had been shot twice — once in the face and once in the chest — injuries investigators described as an execution style killing. Two shell casings were recovered at the scene; the murder weapon was not found.

Early inquiry suggested Cooper had been driven to the remote location, since friends said he had no reason to be in that area. Investigators explored possible links to a drug-involved lifestyle, noting Cooper had prior drug-related offenses. A friend who had been with Cooper on the night he disappeared said he was dropped off in the Salt Lake area, which was the last reported sighting.

After years with no arrests, the case was relaunched and reworked using new DNA evidence. In September 2025, 38-year-old Casteil Slim Franlink Hamlett was arrested and charged with murder, aggravated robbery, and obstruction of justice.

Did anyone who knew Chandler or attended that party near the time of his disappearance see unusual interactions involving Hamlett or others?
