Chad Rockman, a 43-year-old white/Caucasian male from Billings, left for the mountains south of Red Lodge on the morning of April 8, 2020, hoping a hike on the Lake Fork Trail would clear his head. Snow still choked the road and his SUV became stuck, drawing the attention of a passing husband-and-wife hiker who pulled over near Lake Fork Road to help. What began as roadside assistance unraveled quickly: the couple's leashed German shepherd agitated Rockman, according to statements gathered by investigators, and he threatened to kill the dog. As the hikers tried to walk away, Rockman followed with a large stick, smashed a window of the couple's truck, and closed on the husband. The wife deployed bear spray to no effect; the husband, shoved back and fearing the encounter was escalating beyond control, fired once and missed, then fired again as he believed he had to protect himself and his wife. Rockman died of a single gunshot wound.
With no cell service in the canyon, both the couple and Rockman's companion left separately to call 911.
Deputies and the county attorney later concluded the shooting was self-defense. In a letter summarized by local media, Carbon County Attorney Alex Nixon wrote that the husband and wife repeatedly attempted to disengage, that they were threatened with a deadly weapon, and that their account was corroborated by Rockman's friend who had accompanied him that morning. Initial reports from authorities identified Rockman as the victim and noted that three others at the scene—including the shooter—were cooperating with investigators. No arrests were made at the time, and months later prosecutors announced no charges would be filed against the hiker.
The investigation's timeline explains the absence of a named suspect: from the earliest public statements, law enforcement treated the shooter as a cooperating witness while they reconstructed the encounter at the trailhead. When prosecutors formally declined to charge, the case shifted from an open homicide inquiry to a fatal shooting deemed justified under Montana's self-defense law, closing the door on further arrests in connection with Rockman's death.
