Cristian Luna, 24, of Paramount, California, was found dead from a gunshot wound to the head on April 6, 2012. Deputies from the Los Angeles County Sheriff’s Department responded after a 911 call and pronounced him dead at the scene in the 6400 block of San Luis Street shortly after 2 a.m. The case was turned over to sheriff’s homicide detectives.

Investigators concluded Luna was fatally shot, but the motive and circumstances leading to the shooting were not immediately clear. No arrests or suspects were identified at the time, and the sheriff’s department appealed to the public for information, offering anonymity through Crime Stoppers. The investigation remained open but was hindered by a lack of witnesses and concrete evidence.

Does anyone who lived in or near Paramount in April 2012 remember seeing or hearing anything that could help investigators?
