On the evening of April 5, 2025, a shooting outside Foothills Mall in Fort Collins, Colorado, left two brothers dead. Ivan Arreguin Grimaldo, 37, of Greeley, and his younger brother Luis Angel Arreguin, 27, of Westminster, were found on a sidewalk between the mall parking lot and a building with multiple gunshot wounds. Both were taken to a local hospital and later pronounced dead; the Larimer County Coroner’s Office ruled their deaths homicides. The area was briefly placed under a shelter-in-place while officers processed the scene.

Police detained a juvenile the following day. He was identified as 16-year-old Bryan Gallegos and was to be charged as an adult with two counts of first-degree murder and one count of attempted first-degree murder, along with weapon-related counts; a $2 million cash bond was set. Family members said the brothers had been out shopping for shoes just before the attack, and a fundraising page was created to help their mother, Cirila Grimaldo, with funeral expenses.

Does anyone who shopped at Foothills Mall that evening recall seeing anything suspicious or footage that could help investigators?
