The Most Dangerous Job in Mexico?

Last year, a 20-year-old female criminal justice student took a job nobody wanted:  chief of police in a small town in Mexico.  Her predecessor was abducted and murdered, presumably by local drug cartels.  His severed head was left on the steps of the police station.  Still, Marisol Valles Garcia believed she could handle the job.   But after just a few months at work, Valles Garcia fled her town for the United States.  She says that she was threatened almost from the beginning and that her fear "will last a lifetime."   Here's a look at the interview CNN's Kaj Larsen did with Marisol Valles Garcia, shortly after she took the job last year.
