On the morning of November 1, 2020, 21-year-old Oscar Daniel Dicochea of Tucson was fatally shot during a large pre-dawn gathering in a remote desert area near the 2500 block of East Aerospace Parkway, just south of Tucson International Airport. Tucson police responded around 6 a.m. after multiple reports of shots fired; officers were directed off the roadway to where about 50 people had been gathered. Witnesses described a confrontation between two groups that began as a physical fight and escalated into gunfire.

Oscar arrived at Banner University Medical Center’s South Campus by private vehicle and was pronounced dead shortly after arrival. Three other adults were also shot: 23-year-old Isidro Fernando Hernandez-Ortiz later died at the hospital, one woman and another man were treated for non–life-threatening injuries. Multiple vehicles left the scene before officers arrived, and detectives reconstructed events through physical evidence and interviews with those who remained or sought medical care. No arrests have been reported and authorities asked the public for tips. If anyone has information about this shooting or knew Oscar, please share what can help the investigation.
