On the night before the Fourth of July in 2001, a mass shooting at a City Market grocery store and nearby mobile home park in Rifle, Colorado, left four people dead and three others seriously wounded. Victims included Juan Carlos Medrano-Velasquez, 22, his brother Melquiades Medrano-Velasquez, 23, 44-year-old Juan Manuel Hernandez-Carrillo, and 19-year-old Angelica Toscano-Salgado, who had been in the United States 22 days. The attack began around 11:45 p.m. and moved from the store parking lot to the Bookcliff Mobile Home Park, where the Medrano-Velasquez brothers were shot while sitting outside their trailer.

The shooter, 42-year-old Steven Michael Stagner, wounded three additional men and was arrested shortly after. Investigators treated the case as a possible hate crime because the victims were of Mexican nationality and a survivor testified that Stagner used a racial slur before shooting. Stagner pleaded not guilty by reason of insanity; multiple psychiatric evaluations found him legally insane at the time and in December 2002 a judge found him not guilty by reason of insanity and committed him to the Colorado Mental Health Institute for one day to life. A memorial bench now honors the victims.
