No, I hadn't heard of Santiago Meza before.
There are several books on the subject. Sadly I have not gotten around to reading most of them yet. I am reading
The Mexican Mafia by Tony Rafael now. It is pretty good. However it is primarily concerned with La Eme and only peripherally with the much more powerful cartels.
I just bought
The Black Hand by Chris Blatchford which is centered around Boxer Enriquez, who is also Eme, not cartel.
I have heard good things about the book
Narcocorrido by Elijah Wald, which discusses cartel influence in the Mexican entertainment world -primarily music- and the resulting murders or extortions of singers or musicians.
I have also seen good reviews of the book
Herencia Maldita(Cursed Inheritance), a discussion of the cartels by the Mexican journalist Ricardo Ravelo.
Report to Congress on Cartels.
http://www.fas.org/sgp/crs/row/RL34215.pdfBut most of what I know has come from reading an increasing number of articles in the NYT, WSJ, El Paso Times, LA Times which discuss the rising level of cartel directed violence in Mexico and well as the trickle down effect. Kidnapping is really big business in Mexico and it's not just the cartels who are doing it.
Several of the cartels' members are police or military. This brings a new level of violence and brutality to the crime business, not to mention better weaponry..
