On August 9, 2009 the Federal Mexican Police captured Dimas Diaz Ramos aka "El Dimas" or "El Sies" who was in charge of assassinating Mexican President Felipe Calderon. Diaz Ramos worked for the Pacific Cartel and the Sinaloa Cartel headed by Joaquin "El Chapo" Guzman and Ismael "El Mayo" Zambada.

He replaced Jose Lamberto Verdugo Calderon who was in charge of one of the cell's of the Pacific Cartel. Verdugo Calderon was killed during a battle with police on January 22, 2009 and Daiz Ramos assumed his role in the Cartel. Other duties "El Dimas" was in charge of was to move drugs (Marijuana primarily) from the State of Michoacán to Baja California in Tractor trailers that had shipments of avocados and peppers.

The Federal Police began this investigation after a series of threats that came after the President declared war on organized crime and several arrest were made as well as large money seizures made from the Pacific Cartel by the army.

Diaz Ramos was arrested in Culiacan along with Miguel Angel Bagglieto Meraz, Joel Gonzalez Esparza aka "El Raspu', Benni Jassiel Ramirez aka "El Brother" and Jesus Aaron Acosta Montero aka "El Tarrayas".
