More human remains were discovered in the Juarez Valley.
Chihuahua police said they found the human remains of at least 20 people buried in mass graves.
DNA samples were taken to see if they matched those of people who have been reported missing.
Experts said the murders may have occurred between 2001 to 2008. Police said the discovery is the result of an investigation between several United States agencies that are looking for a wanted man.
They have not said if the victims are men or women.
