Brian Castle, a 43-year-old Latino man, was shot and killed on the evening of November 4, 2020, near 109th Street and Figueroa Avenue in the Vermont Vista neighborhood of Los Angeles. The Los Angeles County Medical Examiner-Coroner ruled his death a homicide; Castle died at the scene.

The Los Angeles Police Department canvassed the area, reviewed surveillance footage and sought witnesses, but early leads were limited. Investigators identified several persons of interest in the weeks after the shooting, and no arrests had been announced immediately following the incident.

By December 2020 authorities reported a suspect in custody linked to the case; the identity was not disclosed at that time. What else can readers who knew Brian or who were in the Vermont Vista area that evening share that might help the investigation?
