In the quiet community of Fairview, Utah, the afternoon of June 1, 2020, was shattered by a tragic event that ended the life of 73-year-old Joseph Vallejo. A male resident of the area, his life was abruptly taken in a violent encounter that would soon lead to a startling confession.

On that Monday, at approximately 5:20 p.m., emergency dispatchers in Sanpete County received a chilling phone call. The man on the other end of the line, 32-year-old Michael Hartnell, stated that he had killed someone and wished to turn himself in to the authorities.

Acting on this disturbing admission, deputies from the Sanpete County Sheriff's Office were dispatched to a residence on Cobble Ridge Road, located in the Hideaway Valley area. Upon their arrival, they discovered the body of Joseph Vallejo. He had been fatally shot.

In a swift resolution to the initial phase of the investigation, Michael Hartnell was arrested in connection with the death of his stepfather, Joseph Vallejo. The day after the incident, Hartnell was formally charged with murder, a first-degree felony, and possession of a firearm by a restricted person, a third-degree felony, bringing a somber and swift conclusion to the search for a suspect.
