Psychologist Mónica Ramírez Cano, author of "The Gates of Hell: A Walk Through the Sinister and Dark Corners of the Criminal Mind," is currently one of the most famous criminological profilers in Mexico.
Her desire to analyze what goes through the minds of criminals was born in her when she was 13 years old and now she assures that, to do her job, she has to "be in front, not only of criminals, but of the worst of the bad".
