Nico Valenzuela was 33 when he was shot in Tucson on the evening of July 27, 2023, at a residence in the 1400 block of North Columbus Boulevard. Officers found him in the home with obvious gunshot trauma; he was taken to Banner University Medical Center with life-threatening injuries and died on July 31, 2023.

Police say the shooting followed an argument between Valenzuela and another man that escalated from a verbal dispute into a physical altercation, ending when Valenzuela was shot. Officers located and detained a suspect a short distance from the residence shortly after the shooting. That suspect was identified as 35-year-old Anthony Lee Brown and was arrested on felony charges of aggravated assault with a deadly weapon with serious injury and aggravated assault with a deadly weapon.

The Tucson Police Department later announced the matter would be presented to the Pima County Attorney’s Office for review; as of August 2023 the investigation was ongoing and the case was pending litigation. If anyone witnessed the dispute or has information about the shooting, please share what is known with authorities.
