Richard Alan Casler was 61 when he and 42-year-old Lynn Marie Butler disappeared from a remote campsite on Valdez Creek Road near mile 79 of the Denali Highway during the July 4th weekend of 2015. Friends who expected to meet them for ATV riding on July 2 found the campsite disturbed and Casler’s Ford F-150 abandoned, unlocked, with the keys inside. Blood was later seen on the ground.

Alaska State Troopers searched the area and on the afternoon of July 5 heard noises from a dilapidated trailer. Tactical teams entered and found both Casler and Butler dead. Autopsy results showed Butler died of multiple gunshot wounds; Casler had been shot multiple times and suffered fatal blunt-force injuries. Both deaths were ruled homicides.

Investigators focused on Butler’s estranged husband, Bruce Floyd Dowd Butler, amid reports of a long history of domestic violence and threats. A friend later told authorities Butler confessed to the killings, and on June 20, 2017 Butler was arrested in Wasilla and charged with two counts of first-degree murder. Does anyone have information about Casler or the campsite area that could help fill gaps in the timeline?
