In May of 2021, a police officer's (Bruno Portillo) wife (Reyna Gonzalez-Amador) set out to go on a shopping trip in Atizapan de Zaragoza, Mexico with an elderly man (Andres Mendoza) who had become a friend of the family. He was also somewhat of a charity case for the couple and their children, as he seemed dirty, poor, and down on his luck. They often invited him to their home for meals, and so he was not so lonely. Since he seemed as though he meant them no harm, Reyna wanted his help shopping for supplies for her cell phone business on May 14, 2021. When she had not returned that night, Bruno knew exactly where to turn his attention, Andres. Bruno reported his wife missing, but with barely any help from police at first due to their lack of funding, etc., he took it upon himself to obtain the police street surveillance footage of the street where Andres lived. Reyna was seen entering Andres house, but never exiting with him to go shopping. This is when Bruno knew he had to take officers there to do a search for his wife. After Reyna had been missing for four days, a search was finally able to be conducted, and what Bruno found was horrifying. What was found after this discovery was also never expected and launched and investigation into one of Mexico's most prolific serial killers whose reign of terror has lasted decades.
