Cristorey Gundaya Mariano, a 53-year-old Navy veteran and hospital janitor, was fatally shot on July 23, 2010, in East Oakland. He was returning home from his late-night shift when he was shot near the 5700 block of East 15th Street just before 1:50 a.m. Mariano was described as a well-loved neighborhood figure and a family man; his death left his family and community in mourning.

Authorities have not publicly disclosed a motive, and the circumstances of the shooting remain unclear. His murder followed another high-profile local shooting days earlier and is part of a broader pattern of violence in Oakland at that time. The case remained unsolved as of the latest reports.

If anyone knew Cristorey Mariano or has information about the shooting near East 15th Street on the night of July 23, 2010, please come forward.
