Marisol Valles Garcia took charge on Monday of security in the town, population 10,000, on the US border. The community is around 80 km east of Ciudad Juarez, itself regarded as the most violent city in Mexico.
The former mayor of Guadalupe Distrito Bravos, Jesus Manuel Lara Rodriguez, was killed on June 19 at his home in Ciudad Juarez, after receiving death threats.
Valles Garcia said she will not have to fight the drug gangs, which is the responsibility of other law enforcement agencies. Instead, she will pursue preventive programmes in neighbourhoods and schools, and she will be in charge of reclaiming public spaces for the community.
