In the early morning hours of November 1, 2020, Oscar Daniel Dicochea, a 21-year-old Hispanic/Latino man from Tucson, Arizona, was fatally shot during a large gathering on the city’s south side. He was later pronounced dead at Banner University Medical Center’s South Campus after arriving there with gunshot wounds, one of four people struck by gunfire in the incident.
Loved ones later confirmed his passing in an online obituary, which notes his April 20, 1999 birthdate and records that family and friends gathered for visitation and funeral services at Funeraria del Angel South Lawn in mid-November 2020. Online memorial pages dedicated to him describe a young person deeply loved by his family, friends, and community, with many tributes emphasizing how much he is missed.
The shooting that took Oscar’s life unfolded in a remote desert area near the 2500 block of East Aerospace Parkway, just south of Tucson International Airport. Around 6 a.m., Tucson police received multiple reports of shots fired and responded to the area; when officers arrived, they were directed off the roadway to a site farther south where the gathering had taken place. At the scene, officers found an adult man and an adult woman with obvious gunshot wounds; both were rushed to Banner University Medical Center, where the man, 23-year-old Isidro Fernando Hernandez-Ortiz, died from his injuries while the woman was treated for non–life-threatening wounds. While investigators were still working at the scene, police were notified that two additional gunshot victims had arrived at a hospital by private vehicle. One of them was Oscar, who was pronounced dead shortly after arrival; the fourth victim, another adult male, was treated for what were described as non–life-threatening injuries.
Investigators later learned that roughly 50 people had gathered in that desert area before dawn, and witnesses described a confrontation between two groups that escalated from a physical fight into an exchange of gunfire. Multiple vehicles reportedly fled before officers reached the scene, leaving detectives to reconstruct events through physical evidence and interviews with those who remained or later sought medical care. Both local television coverage and later case summaries emphasize that detectives interviewed witnesses at the scene and at the hospital and were actively pursuing leads in the days following the shooting.
As of the most recent publicly accessible updates, there have been no reports that any suspect has been arrested or formally identified in connection with the gunfire that killed Oscar and Isidro and wounded two others. Early news reports noted that no suspect was in custody and that authorities were appealing for information from the public, directing anyone with knowledge of the shooting to contact 911 or the anonymous tip line 88-CRIME. Later online case listings, updated through 2025, continue to present the incident as an open homicide investigation and invite additional information, underscoring that, at least in the public record, the circumstances and responsible individuals have not yet been fully resolved.
