Gonzalo Inzunza Inzunza (17 August 1971 – 18 December 2013), commonly referred to by his alias El Macho Prieto, was a Mexican drug lord and high-ranking leader of the Sinaloa Cartel, a Mexican transnational criminal organization. He worked as the cartel's assassins chief under the tutelage of Ismael "El Mayo" Zambada and Joaquín "El Chapo" Guzmán, the two top leaders of the cartel.

Criminal career

Inzunza Inzunza was born in the state of Sinaloa in western Mexico on 17 August 1971. He worked as the leader of a circle of assassins for the Sinaloa Cartel, a drug trafficking organization headed by the drug lords Ismael "El Mayo" Zambada and Joaquín "El Chapo" Guzmán. When he first started in organized crime, Inzunza Inzunza operated in Culiacán and in other regions across Sinaloa. The Mexican authorities believe that he may be responsible for over 80 murders during his tenure in Sinaloa, including the killings of at least a dozen police officers. 

On 5 May 2005, he was arrested in Mazatlán by the local police with six of his men. The police confiscated several assault rifles, handguns, grenades, and launchers. The arrest of Inzunza Inzunza was initially reported by a photojournalist, but the drug lord never made it to prison; unconfirmed reports stated that he bribed the police to avoid prison. He was later transferred by the top echelons of the Sinaloa Cartel to the states of Baja California and Sonora around 2010. His base of operations was in Mexicali, where he coordinated drug trafficking activities. Inzunza Inzunza was characterized for using violence as a control factor in the territories he controlled for the Sinaloa Cartel.

Bounty

Inzunza Inzunza, also known by his aliases of El Macho Prieto, El MP, and El Once, was placed on the most-wanted drug traffickers list under the Foreign Narcotics Kingpin Designation Act by the U.S. government on 1 June 2011, along with Manuel Torres Félix (alias "The Crazy One"), another high-ranking lieutenant of the Sinaloa Cartel. The PGR offered up to $3 million Mexican pesos for information leading to their arrests.

Death

Inzunza Inzunza was reportedly killed in a gunfight with Mexican Marines in Puerto Peñasco, Sonora, on 18 December 2013. The Sonora authorities confirmed that the shootout, which occurred at around 04:00 A.M. that day, left a total of five dead and three vehicles incinerated. Authorities confirmed that two gunmen were killed on the scene during the firefight, while two others died by wrecking their vehicle while attempting to flee the crime scene; the remaining gunman died of gunshot wound complications. Preliminary reports stated that gunmen held several hostages at a hotel during the raging gunfire, but the Sonora authorities denied the authenticity of these initial reports. The shootout was reported to have lasted at least four-hours. An eye-witness close to the crime scene said to the press that a police helicopter was involved in the fire exchange from mid-air with the gunmen, who fired at the chopper from the ground.

According to police reports, the incident began when the Mexican authorities chased a white Chevrolet pick-up truck in Sonoyta, Sonora following a reported homicide; the police later caught up to the vehicle in Puerto Peñasco after the men in the vehicle opened fire at them. Following the shootout, the local authorities ordered the school district of Puerto Peñasco to suspend classes for the day. The U.S. Consulate in Nogales, Sonora, emitted a travel warning through Twitter advising U.S. tourists to stay indoors until the gunfire was over. Puerto Peñasco (known in English as "Rocky Point") is Sonora's major tourist attraction a major tourist destination for U.S. citizens given its 50 mi (80.4 km) proximity from the U.S.-Mexico border.
