Christopher Lee Gallegos, 28, was shot to death outside an apartment building in the 2600 block of Acacia Avenue in Rifle, Colorado, on a Wednesday evening in late March 2017. The Garfield County Coroner’s Office confirmed the cause of death as a gunshot wound to the head; it was the county’s first homicide that year.

Investigators identified the suspect as Michael Francis Montgomery, then 45 and Gallegos’s father-in-law. Authorities said they did not believe the shooting was random. Montgomery allegedly went to the residence seeking another man over a monetary dispute; an argument and a single gunshot were reported by witnesses. Montgomery fled and was the subject of a six-month manhunt before he was located in Oregon and arrested in September 2017.

A judge later ruled there was insufficient evidence of premeditation and bound the case over as second-degree murder rather than first-degree. Does anyone have information about Christopher, the dispute, or what happened that night?
