Fred Mustain, 38, was found shot multiple times at a construction site at 527 E. Vine Street in Murray, Utah, on the evening of September 5, 2015. A bicyclist heard him calling for help around 9:20 p.m.; emergency crews took him to Intermountain Medical Center, where he died in the early hours of September 6.

Initial investigations produced no immediate suspects or clear motive. His family, including his partner and son, described him as a good man and remained without answers. Court records show Mustain had prior charges, including aggravated robbery and drug possession, and authorities noted some known gang affiliations.

In December 2024 the Murray Police Department renewed the cold-case probe, offered a $5,000 reward, and said possible suspects had been identified while asking the public for help to substantiate evidence. No arrests have been made and the case remains open. If anyone knew Fred or has information about the shooting, please contact investigators.
