Theory Behind the Durango Bodies

I'd missed this report from the AP a couple of days ago:

The Sinaloa cartel had seemed immune to the kind of missteps, mindless violence and internal power struggles that have plagued other drug gangs, to the extent that most Mexicans believed the Sinaloa cartel was either exceedingly sophisticated or in cahoots with the government.

But the portrait now emerging from the 219 corpses is of a cartel that is riven by internal cracks, according to the official.

In recent months, at least two local groups sought to break off from Sinaloa and control the drug shipment routes through Durango for themselves, the official said. A third group, known as the "M's," remained loyal to Sinaloa boss Joaquin "El Chapo" Guzman, who has been named one of the richest and most influential people in the world by Forbes magazine, with a fortune of more than $1 billion.

A leading member of the "M's" and the fourth-highest ranking Sinaloa operator in Durango, Bernabe Monje Silva, was arrested by federal police on March 27 and led police to the grave sites, the police official said.

It goes along with recent reports of Los M's and Gente Nueva fighting in Durango.

[Obligatory point: Forbes saying Chapo has $1 billion is no more trustworthy than me saying it, or the clerk at your local McDonalds saying it.]
