In the quiet neighborhood of North-Central Phoenix, 30-year-old David Denogean, a beloved high school teacher and track coach, was taking his white Labrador mix, Evie, for their routine evening walk on November 25, 2022. As he strolled near 12th Street and Maryland Avenue, listening to a podcast, an unknown man ran up from behind him. The assailant then circled in front of Denogean, raised a handgun, and fired multiple times in an apparently unprovoked attack.
The brazen shooting occurred in a well-trafficked area, with some witnesses sitting on the patio of a nearby restaurant. Denogean was rushed to a local hospital where he succumbed to his injuries.
The investigation into the seemingly random act of violence has been fraught with frustration for Denogean's family, who have actively sought to keep his case in the public eye. For a long time, there were few official updates on the investigation, leaving his loved ones to wonder if justice would ever be served. The Phoenix Police Department released blurry surveillance footage of the suspect, described as a white or Hispanic male in dark clothing, but this did not immediately lead to a breakthrough in the case. The killing of the 6-foot-4, 240-pound man, who was known for his kind and gentle nature, sent shockwaves through the community, leaving friends, family, and students to mourn a man who was a mentor and a friend to many.
In a surprising turn of events, it was later revealed through public records that investigators had identified a suspect two years prior to the information becoming public. The suspect, Eduardo Quintero, was already in custody and charged with a strikingly similar homicide that took place just one day after Denogean was killed. In that case, Quintero was sentenced to 25 years in prison for the unprovoked murder of Joseph Patruno at a gas station. While police have confronted Quintero about Denogean's murder and reportedly have video evidence of him stalking and killing the teacher, he has not been formally charged with the crime. The case officially remains open, and Quintero has denied any involvement. The revelation that a suspect had been identified for years without the family's knowledge added another layer of pain to their tragic loss.
