On July 3, 2015, 42-year-old Lynn M. Butler, a caucasian woman camping near mile 79 of the Denali Highway with her friend, 61-year-old Richard A. Casler, was reported missing after the pair failed to return. Responding Alaska State Troopers found spent evidence and damage suggesting gunfire around the campsite, their vehicle, and a nearby camper. A ground-and-air search fanned out over the remote corridor between Paxson and Cantwell. Two days later, on July 5, troopers searching the area heard unexplained noises coming from a dilapidated trailer, established a perimeter, and repeatedly tried—without success—to make contact with anyone inside. Special Emergency Reaction Teams were called in; when they finally entered, they found Lynn Butler and Richard Casler dead. Troopers soon identified them publicly and said both had been killed by gunshot wounds.
The Alaska Bureau of Investigation took over as a double-homicide inquiry. Court records later summarized evidence knit together from the scene and beyond: items collected at the murder site, cell-phone data, witness statements, and communications attributed to a suspect. Autopsy findings would specify that Lynn Butler died of gunshot wounds, while Casler had been shot and beaten, adding a grim layer to an already stark crime in an isolated landscape.
Nearly two years after the killings, investigators made an arrest. In June 2017, troopers detained 42-year-old Bruce Floyd Dowd Butler—Lynn Butler's estranged husband—at his home in Wasilla and charged him with two counts of first-degree murder. A complaint filed in Superior Court pointed to prior domestic-violence incidents and described two alleged admissions: one to a former friend, and another to a person the suspect met at a Sterling state-park campground earlier that month. Authorities said the victims' bodies had been concealed at a remote site near mile 79, consistent with the rugged terrain where search teams had first converged during the Fourth of July weekend in 2015.
Public reporting identifies Lynn M. Butler, 42, as the victim and documents her death on July 5, 2015; it also records the subsequent arrest and charging of a suspect in 2017. Later summaries list her as a 42-year-old female lost to gun violence on that date, reinforcing the timeline that began with a missing-persons call and ended with an arrest two summers later.
