Rene Enriquez was a leader in one of America's most violent gangs, the Mexican Mafia. He's serving 20 years to life in California for murders he committed for the gang. While in prison, Enriquez rose to a powerful position in the gang. But then he had a change of heart. Over the past year and a half, American RadioWorks' Michael Montgomery has been following Enriquez's struggle to leave the gang life. Here are excerpts from their interviews.
