Luis Mario Lizarraga, a 34-year-old Latino man, was fatally shot on August 31, 2004, in Paramount, California, according to Los Angeles County coroner records. The shooting left investigators with limited public detail about what exactly occurred that night.

Authorities launched an investigation that included multiple leads and witness interviews. Reports note arrests and interrogations over the years, but say concrete evidence directly tying anyone to the killing has not been established and prosecutions have struggled for lack of definitive proof. The case has been linked in reporting to the broader problem of gang-related violence in the area at the time.

Lizarraga was remembered by friends and family as a beloved community member. Anyone who has information about his death or who remembers events around August 31, 2004, in Paramount is asked to come forward.
