Oscar Tatenco was 28 when he was shot and killed on June 29, 2003, in Paramount, California. The Los Angeles County coroner’s records list gunshot wounds as the cause of death, and the shooting occurred in the vicinity of the Los Angeles River.

Homicide detectives opened an investigation but faced limited witness cooperation and the slow work of gathering forensic evidence. Several leads were pursued early on, yet no arrests were made in the immediate aftermath and no suspect is identified in the material provided.

The case illustrates the difficulties of solving shootings in areas with high crime and scarce resources, and the impact an unresolved homicide has on a victim’s family and community. If anyone knew Oscar Tatenco or witnessed activity near the Los Angeles River in Paramount around June 29, 2003, please come forward with information.
