In the summer of 2019, the life of 20-year-old Tyler Hayden, a White male from Sidney, Montana, was cut short in a fatal encounter. On the evening of July 2, 2019, Hayden was shot and killed in the parking lot of a Loaf-N-Jug convenience store in his hometown. The incident stemmed from a history of confrontations between Hayden and another young man from Sidney, Kyle Lee Severson.

On that Tuesday evening, Severson was in a vehicle with his girlfriend, their three-year-old daughter, and his girlfriend's sister. Hayden arrived at the same convenience store moments later with a friend. After Hayden exited the store, he approached the vehicle where Severson was a passenger. As Hayden neared the open rear window, Severson, fearing for his and his daughter's safety, fired a handgun at close range, striking and killing Hayden. Severson immediately had his girlfriend drive him to the police station, where he admitted to the shooting, claiming self-defense.

Kyle Lee Severson was arrested and charged with deliberate homicide. During his trial, the defense argued that Severson acted out of fear for his life, citing past altercations with Hayden, including an alleged armed robbery. The prosecution maintained that Severson was the aggressor and that there was no evidence Hayden was armed at the time of the shooting. A jury ultimately found Severson guilty of mitigated deliberate homicide, and he was sentenced to forty years in the Montana State Prison.

However, the legal saga did not end there. Severson appealed his conviction, and in April 2024, the Montana Supreme Court reversed the decision. The higher court ruled that the cumulative effect of errors during the trial, including the prosecution's failure to disclose favorable evidence to the defense, had denied Severson his constitutional right to a fair trial. The conviction was overturned, and the case was remanded for a new trial.
