Andres Filomeno Mendoza Celis, also known as "El Chino" and "Cannibal of Atizapan," is among the most notorious serial killers in Mexico.

The 74-year-old former resident of Atizapan de Zaragoza in the state of Mexico passed off as an elderly gentleman to his neighbors. However, El Chino harbored a dark secret, as he murdered more than 30 people, mostly women, and ate their flesh.

Mendoza, a former butcher, made a living by renting out rooms in his house. A man who rented a room in Mendoza's home remarked in the latest episode of the documentary series called "Caníbal, indignación total" that the serial killer shared the flesh of his victims with his neighbors and local police officers.

The man noted that on several occasions, El Chino would pass human flesh off as "carnitas" (braised pork) or "carne enchilada" (meat seasoned with chile), which was what he said he made. The serial killer also sells the victims' flesh, passing it off as pork or wild boar meat.

El Chino's Neighbors in Mexico Had No Idea He Was a Serial Killer and Cannibal

According to Mexico Daily News, Andres Filomeno Mendoza Celis originally came from San Sebastián Río Dulce, Oaxaca, and only moved to the Las Lomas de San Miguel neighborhood of Atizapan de Zaragoza. There, he got along well with his neighbors. At one time, he even became a local association leader.

According to El Pais, neighbors told the media that he would often visit his last victim, former girlfriend Reyna Gonzalez, in her small cellphone store near his house. The two would often talk, and El Chino would also bring her food every now and then.

The new documentary about El Chino aired on Mexican TV last June 27. There, it was revealed that he would often go home to San Sebastián Río Dulce and bring some meat and clothes. Mendoza often came home with a cooler. 

Being a former butcher, many of his neighbors did not question where he got the meat. But his neighbors reportedly spent time with him and ate the meat he brought.

Journalist and academic Gabriela Warkentin said in the documentary that El Chino used to tell his neighbors in Atizapan de Zaragoza that he had wild boar from Oaxaca, and when he was in Oaxaca, he would say he had pork from Mexico state to cover up the fact that he was handing out human flesh.

Missing Girlfriend Led to Mexico Police Investigating Serial Killer 'Cannibal of Atizapan'

Police discovered El Chino's criminal activities in May last year after some people reported that his last victim had gone to his home before she disappeared.

According to Daily Mail, Reyna Gonzalez tried to end her relationship with Mendoza. However, El Chino would not take the break-up lightly and drove a knife into her chest before cutting off her limbs and stuffing her body parts into bags.

Police raided his Atizapan home, including the rooms he was renting out. There, they discovered evidence surrounding Mendoza's horrifying activities in the basement, where the serial killed, tortured, and butchered his victims.

These include knives, cooking utensils, and books of anatomy. Police also found pieces of skin and a plate of tortillas with a piece of human meat. Police also found the bags containing Gonzalez's body, which had been placed on top of a table. 

Following his arrest, Mendoza confessed to as many as 30 murders over the course of two decades and ate some of the remains of his victims.

He kept detailed notes about his killings, which showed that he murdered between 30 and 40 women and also admitted to eating parts of them. Daily Mail reported that he allegedly videotaped his killings as well.

As they raided Mendoza's home, police not only found the body of Gonzalez but his other victims as well. Police reportedly discovered more than 4,000 bones in El Chino's home, many of which were buried under the concrete in the basement.

The human remains are believed to have belonged to 19 victims, 17 of whom were women, one man, and a child. The "Cannibal of Atizapan" is now serving a life sentence behind bars.

According to National Autonomous University psychology academic Feggy Ostrosky, who was interviewed for the documentary, Andres Filomeno Mendoza Celis' case is "one of the most atrocious" that has been documented. Ostrosky noted that women were "animals" for the "Cannibal of Atizapan."
