Arturo Gallegos Castrellon, a 32 year old man, has confessed that he was responsible for most of the shootings since August 2009 in Ciudad Juarez, a city in Mexico. This man is the leader of the drug gang Los Aztecas in this city. He orders all of these killings to be done and leads others in the gang to commit these murders. This arrest has a huge impact to hopefully stop the violence in Ciudad Juarez, but residents don't believe that it will fully cease.
