Mauricio Arnoldo Martinez, a 32-year-old Latino man, was fatally shot in South Park, Los Angeles, on April 21, 2019. The Los Angeles County Medical Examiner-Coroner ruled the death a homicide after investigators determined he had been shot multiple times and died at the scene.

Detectives canvassed the neighborhood, interviewed witnesses and reviewed surveillance footage, but the investigation struggled early on because there were few leads and witnesses were reportedly reluctant to come forward. Detectives continued to develop the case in the months that followed, citing forensic evidence and witness testimony as part of their work.

An arrest was later announced and the suspect was charged with first-degree murder; the prosecution relied on the evidence gathered during the investigation while the defense challenged witness credibility and aspects of the forensic case. The accused was convicted at trial, bringing a legal resolution to Martinez’s killing.

If anyone knew Mauricio or has information about the shooting on April 21, 2019, please come forward.
