Steven Campbell Sr., 53, was fatally shot in the head outside his mother’s home in the 800 block of Marcolin Street in Houston on June 10, 2022. He was pronounced dead at the scene. His 30-year-old nephew, Steven Campbell Jr., also was shot — in the buttocks — and was taken to a nearby hospital in critical condition but expected to survive.

Police say Fitzgerald Campbell, 55, was arrested near the scene and charged with murder and the aggravated assault of a family member. Authorities reported Fitzgerald was walking in the area armed and, while reportedly angry, encountered his nephew and brother and shot the two men, shooting the nephew first and then the brother. The motive remains unclear and the investigation is ongoing.

Does anyone have information about the Campbells or the events on Marcolin Street that could help investigators?
