On the afternoon of Thursday, September 22, 2022, deputies with the Yuma County Sheriff’s Office responded to a report of two unresponsive people near County 13th Street and Avenue F in Yuma. They found 28-year-old Kristin Carrillo and 31-year-old Daniel Herrera Jr., both of San Luis, Arizona, with apparent gunshot wounds. Fire personnel pronounced both deceased at the scene and the Sheriff’s Office opened a homicide investigation.

Within about ten minutes of that discovery, a separate call reported a third shooting victim, 45-year-old Juan Luna-Montijo, found with gunshot wounds on Mojave Lane. Investigators have said they believe the two scenes are related. No arrests have been announced and authorities say the investigation has been hampered by a lack of witnesses coming forward.

Anyone with information about Kristin Carrillo, Daniel Herrera Jr., or the shootings on September 22, 2022, is asked to contact the Yuma County Sheriff’s Office.
