The following is directly from the La Paz Gringos group (member StefenMWest):
The Beltran Leyva Cartel was created by 4 brothers, Carlos (in prison since 2009), Hector (at large with $5 million dollar bounty), Alfredo (in prison since 2008) and Arturo (killed by police in 2009). They were once one of Mexico’s most powerful cartels and are now considered disbanded by some authorities since the arrest af a top lieutenant in 2011.
The shooting victim at the Bismark(cito) the other day (May 10, 2012), Zeferino Félix Beltrán, was a nephew of Hector, the Beltran brother still at large.
In the last 6 months, the police have intercepted 2 large shipments of drugs, one of 10Kg of cocaine and another 13Kg of heroin at Pichilingue (La Paz) on the Baja Ferry.
It was just over two years ago, in Jan of 2010 that “el Teo”, leader of the Culiacan Cartel was arrested in the Fidepaz area (La Paz) where he had been living for more than a year.
