Maria Pastora Reyes, 21, was found murdered in a dirt field in Chino Hills on January 4, 2002. She had been brutally stabbed to death and was last seen the previous night between 10:30 and 11:30 p.m. when she left a location in Santa Ana.

Witnesses near the crime scene reported seeing a group of Hispanic males in a brown 1990s Chevy van in the area around the time of the killing; those sightings became an early focus of the inquiry. The investigation stalled despite those leads, and the case remains unsolved. The San Bernardino County Sheriff’s Department continues to seek information and accepts anonymous tips as part of a wider review of cold cases.

If anyone remembers seeing a brown 1990s Chevy van in the Chino Hills area the night of January 3–4, 2002, or has other information about Maria Pastora Reyes’ movements that evening, please come forward.
