On the evening of July 3, 2001, Juan Manuel Hernandez-Carrillo, 44, was fatally shot while using a payphone outside the City Market grocery store in Rifle, Colorado. The shooting was part of a broader rampage by 42-year-old Steven Michael Stagner, who then went on to kill three other people and wound three more at a nearby mobile home park. The other deceased were Angelica Toscano-Salgado, 19, and brothers Melquiades Medrano-Velasquez, 23, and Juan Carlos Medrano-Velasquez, 22. All victims were of Mexican nationality.

Rifle police arrested Stagner minutes after the attacks and recovered the firearm used. He was charged with multiple counts of first-degree murder and attempted murder. Mental-health evaluations became central during the legal process, and Stagner was found legally insane at the time of the shootings and was committed to the Colorado Mental Health Institute in Pueblo for a term of one day to life.

Anyone who knew Juan Manuel Hernandez-Carrillo or was in Rifle that night and has information is asked to share what they remember.
