Guadalupe Castaneda was 29 when she was fatally shot on September 8, 2006, in the Hansen Dam area of Los Angeles County. The scene reportedly lacked immediate witnesses, which complicated the early investigation.

Detectives interviewed people and pursued leads that eventually produced arrests of individuals believed connected to the crime, and the suspects later faced charges. Court proceedings involved evidence review, witness testimony, and forensic analysis as prosecutors sought to link the suspects to Guadalupe’s killing.

If anyone knew Guadalupe, witnessed the shooting, or has information about what happened around Hansen Dam that day, please share what is known with investigators.
