Woman anti-crime crusader gunned down in Mexico

A mother who waged a two-year battle to bring her daughter’s killer to justice has been shot to death, possibly by the same man suspected of murdering the teenager.

A security video recording shows masked men pulling up in a car in front of the governor’s office in the northern city of Chihuahua. One appeared to exchange words with anti-crime crusader Marisela Escobedo Ortiz, who was holding a vigil outside.
