men to any murders committed there. They said they saw altars and other ritualistic belongings, but did not find any traces of blood. No men were arrested at the scene, but the police managed to arrest a lady called María Teresa Quintana Rodríguez, sister of one of Constanzo's lovers and henchmen. The police also discovered that Aldrete's purse and other belongings were left behind, which prompted them to conclude that Constanzo probably murdered her because she knew too much about the inner workings of his cult group. The police stated that they did not see Aldrete with the group when they arrived in Mexico City. They thought that Constanzo might have buried her somewhere in the city. U.S. authorities, however, believed that Aldrete purposely left her belongings behind to confuse investigators and make it appear that she was dead. On 24 April, the police arrested Víctor Manuel Antúnez Flores and Salvador Antonio Villaluz, who were hiding in one of Constanzo's properties in the Juárez neighborhood. Death of Constanzo The Mexico City police department noticed that the Matamoros killings were similar to murders carried out in Mexico City between 1987 and 1989. After consulting local witchcraft practitioners and sorcerers, the police heard that Constanzo was probably hiding in Cuauhtémoc, one of the city's boroughs. Another contact told the police that there was an address of interest in the Verónica Anzures neighborhood, next to Cuauhtémoc. The police department sent 16 officers to search the area. At a supermarket, they interrogated a shoemaker who claimed to have seen a woman who matched Aldrete's description. The police then spotted a man at the supermarket who was attempting to buy large amounts of groceries with U.S. dollars. They followed the man and saw that he was living at an apartment on Río Sena. By the end of the week, the police concluded that the man was De León and that he was buying groceries for Constanzo. On 6 May 1989, the police surrounded the building and waited for traffic to subside before raiding the premises. However, a black vehicle pulled up in front of the apartment complex and the police walked over to investigate. Constanzo noticed the police from the window of his apartment and opened fire at the officers who were at ground level. Constanzo threw golden coins and paper money from the window, and burned some of his money on a stove. Constanzo
