El Blog Del Narco.

Score another one for new media: an anonymous, twenty-something blogger has become Mexico's go-to for information on the country's deadly drug war. Blog del Narco, launched in March, includes postings from both drug traffickers (such as warnings and even a beheading) and law enforcement (crime scenes accessible only to the police and military). In one case, Blog del Narco helped lead to a major arrest, when a video posted detailed a prison warden's system of setting inmates free at night to carry out drug cartel murders.

The AP tracked down this mysterious blogger, who revealed that he is a student in northern Mexico majoring in computer security. When he launched the blog, he intended it to be a hobby, but has grown faster than his wildest expectations, now receiving 3 million hits weekly. The blogger also uses Facebook and Twitter.

Since late 2006, over 28,000 people have died in drug-related violence in Mexico. The country has become one of the most dangerous places in the world for journalists: at least 30 have been killed or have disappeared since 2006 and many news organizations have been attacked with bombs and gunfire. Many journalists engage in self-censorship to avoid crossing the increasingly brazen cartels that attempt to control the press. On August 7, hundreds of journalists marched in Mexico City to protest escalating violence against their peers.

This helps explain why Blog del Narco, now an essential resource for Mexicans concerned about which streets to avoid during shootouts, engages in intense anonymity.

The AP listed some examples of recent posts:

* A video of a man being decapitated. While media only reported police finding a beheaded body, the video shows the man confessing to working for drug lord Edgar "La Barbie" Valdez Villareal, who is locked in a fight with both the Beltran Leyva and Sinaloa cartels;

* The prison warden affair, which unfolded in a video of masked members of the Zetas drug gang interrogating a police officer, who reveals that inmates allied with the Sinaloa cartel are given guns and cars and sent off to commit murders. At the end of the video the officer is shot to death;

* Links to Facebook pages of alleged traffickers and their children, weapons, cars and lavish parties;

* Photos of Mexican pop music stars at a birthday party for an alleged drug dealer's teenage daughter in the border state of Coahuila, across from Texas.
