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 as the regional leader of the cartel in the states of Baja California and Sonora. His base of operations was in Mexicali, where he coordinated marijuana and cocaine shipments through the Calexico–Mexicali border region. On 18 December 2013, Inzunza Inzunza was killed in a shootout with Mexican authorities in the resort area of Puerto Peñasco, Sonora. Before the gunfight was over, several of his gunmen took the corpse of the drug lord with them.
