A friend reported being unable to contact 25-year-old Harry Nguyenhuy Doan on the evening of August 21, 2023, prompting Phoenix police to check his apartment at 3030 North 7th Street. Officers found Doan inside with multiple gunshot wounds; he was pronounced dead at the scene.

Detectives say their investigation uncovered that Doan had been in a relationship with a woman whose former boyfriend, 26-year-old Rene Penaloza, had allegedly made threats against Doan. Police located Penaloza in the Tucson area, stopped his vehicle with assistance from the Department of Public Safety, and arrested him.

Does anyone have information about Doan, his movements in Phoenix before August 21, or the people involved that could help clarify what happened?
