Question: How much money is offered by the U.S. government for information that leads to the arrest and/or conviction of the head of the cartel that is currently fighting the Knights Templar Cartel and Los Zetas for control of the city of Guadalajara?

<P0-S0> The 2010 San Fernando massacre, also known as the first massacre of San Fernando, was the mass murder of 72 illegal immigrants by Los Zetas drug cartel in the village of El Huizachal in the municipality of San Fernando, Tamaulipas, Mexico. <P0-S1>  The 72 killed—58 men and 14 women—were mainly from Central and South America, and they were shot in the back of the head and then piled up together. <P0-S2>  The bodies were found inside a ranch on 24 August 2010 by the Mexican military after they engaged in an armed confrontation with members of a drug cartel. <P0-S3>  They received information of the place after an Ecuadorian survived a shot to the neck and face, faked his death, and then made his way out of the ranch and up to a military checkout to ask for help. <P0-S4>  There were only three survivors. <P0-S5>  Investigators later mentioned that the massacre was a result of the immigrants' refusal to work for Los Zetas, or to provide money for their release. <SEP> <P1-S0> Nemesio or Rubén Oseguera Cervantes (born July 17, 1966), commonly referred to by his alias El Mencho, is a suspected Mexican drug lord and leader of the Jalisco New Generation Cartel (CJNG), a criminal group based in Jalisco. <P1-S1>  He is one of Mexico's most-wanted men, and the U.S. government is offering up to US$5 million for information that leads to his arrest and/or conviction. <P1-S2>  He is wanted for drug trafficking, organized crime involvement, and illegal possession of firearms. <P1-S3>  He is reportedly responsible for coordinating drug trafficking operations in the Americas, Europe, Asia, and Africa. <P1-S4>  Under his command, the CJNG became one of Mexico's leading criminal organizations. <SEP> <P2-S0> The 2012 Nuevo Laredo massacres were a series of mass murder attacks between the allied Sinaloa Cartel and Gulf Cartel against Los Zetas in the border city of Nuevo Laredo, Tamaulipas, across the U.S.-Mexico border from Laredo, Texas. <P2-S1>  The drug-violence in Nuevo Laredo began back in 2003, when the city was controlled by the Gulf Cartel. <P2-S2>  Most media reports that write about the Mexican Drug War, however, point to 2006 as the start of the drug war. <P2-S3>  That year is a convenient historical marker because that's when Felipe Calderón took office and carried out an aggressive approach against the cartels. <P2-S4>  But authors like Ioan Grillo and Sylvia Longmire note that Mexico's drug war actually began at the end of Vicente Fox's administration in 2004, when the first major battle took place in Nuevo Laredo between the Sinaloa Cartel and Los Zetas, who at that time worked as the armed wing of the Gulf Cartel. <SEP> <P3-S0> The Jalisco New Generation Cartel (Spanish: "Cártel de Jalisco Nueva Generación" , "CJNG" and "Matazetas") is Mexican criminal group based in Jalisco and headed by Nemesio Oseguera Cervantes ("El Mencho"), one of Mexico's most-wanted drug lords. <P3-S1>  The CJNG are currently fighting the Knights Templar Cartel and Los Zetas for control of the cities of Guadalajara, Jalisco and the states of Michoacán and Veracruz. <P3-S2>  The CJNG also operates in the states of Nayarit, Colima, and Guanajuato. <P3-S3>  While this cartel is best known for its fights against the Zetas, it has also been battling La Resistencia for control of Jalisco and its surrounding territories.
