Robert Joe Mageno, 75, was killed on Easter Sunday, March 31, 2024, at a rented-room residence on Canberra Way in Riverside, California. Family remembered him as a quiet man who loved his children, family gatherings and 1960s–70s music. Several people leased rooms in the home.

Around noon an argument erupted between resident 27-year-old Christopher Jacob Lennox and his visiting girlfriend. Police say Lennox retrieved a handgun and shot the girlfriend; as she fled, Mageno came out of his room and was also shot. Witnesses called police; officers found Lennox at the house and took him into custody without incident. Paramedics pronounced Mageno dead at the scene. The wounded girlfriend was taken to hospital in critical condition and later recovered. A handgun believed to be the weapon was recovered inside the home.

Lennox was booked on a $1 million bail and charged with murder, attempted murder, domestic violence and related enhancements; he pleaded not guilty at arraignment. If anyone knew Robert Mageno, his life in Riverside, or witnessed what happened that day, please share what you remember.
