Melvin Johnson, 39, was fatally shot on December 27, 2016, in East Oakland while driving near a street memorial for his son and grandson. He died later at a hospital from his injuries. His son, 20-year-old Andrew Thomas, and 16-month-old grandson, Drew Leon Deon Jackson, had been killed in August 2013 while sleeping at a relative’s home during a birthday visit; those earlier deaths prompted Johnson to become a vocal advocate against street violence.

At the time of this report, police had not identified a motive or made any arrests in Johnson’s killing. Authorities are offering up to $10,000 for information leading to an arrest in his murder, and up to $30,000 for tips related to the deaths of his son and grandson. Johnson’s death is cited alongside ongoing gun violence and high homicide levels in Oakland, underscoring the toll on families and neighborhoods.

If anyone has information about these killings or recalls seeing anything near the memorial on December 27, please contact investigators.
