Douglas Green was killed in Inglewood, California, on May 20, 1972, by a single bullet wound to the chest. Local authorities opened an immediate investigation into the shooting.

Detective Sergeant Thomas Miller led the inquiry, which resulted in the arrest of three suspects — Michael Concepcion, Lewis White, and a third unnamed individual — all reported to be between 15 and 16 years old at the time. Prosecutors charged them with first-degree murder, presenting witness testimony and forensic evidence and arguing the killing was premeditated. The defense raised diminished capacity related to the defendants’ ages, but juries ultimately returned guilty verdicts.

The case produced extended legal proceedings with appeals and retrials that centered in part on the effectiveness of defense counsel; the convictions were ultimately upheld and the defendants received lengthy prison terms. Does anyone have memories of the case or information about Douglas Green or the investigation?
