Benjamin Franklin Williams, 60, was one of three men shot dead inside a North Oakland home on May 23, 2015. The shooting happened in the 900 block of 54th Street around 2:40 p.m.; Darryl Robinson, 59, and Raymond E. Garza, 53, were also killed. The gunman, Damien Robinson, shot his father and two friends during a confrontation, then barricaded himself inside the house before police arrested him.

At trial the jury convicted Damien Robinson of two counts of second-degree murder for the deaths of Darryl Robinson and Benjamin Franklin Williams, and one count of voluntary manslaughter for Garza. The defense said Robinson acted in self-defense and raised concerns about crime-scene contamination; the prosecution argued the killings were deliberate. Body-camera footage showed officers attempting life-saving measures amid a chaotic scene.

Does anyone have memory of the neighborhood or information about Benjamin Williams and the others that could shed light on what led up to that afternoon?
