On a morning in August 2021, 30-year-old Matthew Lujan was shot and killed inside his family home in Phoenix, Arizona during a domestic dispute that also left his parents, Lewis and Irene Lujan, dead. The confrontation began as an argument between Matthew’s older brother, Brandon Michael Lujan, and their parents; Matthew intervened and a physical fight followed. During the altercation, Brandon pulled out a handgun and shot Matthew multiple times. When Lewis and Irene came out of a bedroom they were also shot; all three suffered multiple gunshot wounds.

The day after the killings, Brandon went to a hospital with an ankle injury from the fight and told hospital staff what had happened; staff contacted the police and officers located the three bodies at the home. Reports say the dispute was over Brandon and his wife being asked to leave the parents’ house. Does anyone have information about the family, the events that led up to the argument, or knew Matthew personally?
