Andrés Filomeno Mendoza Celis dies in Mexican prison

Andrés Filomeno Mendoza Celis, known as the “Monstruo de Atizapán” or the “Caníbal de Atizapán,” died on October 29, 2026, at the age of 78. He passed away while in custody at the Tenango del Valle Penitentiary and Social Reinsertion Center in the State of Mexico.

Mendoza Celis was a serial killer linked to the deaths of at least 19 people, including 17 women, a man, and a minor. His crimes were discovered in May 2021 following the disappearance of Reyna González Amador. Authorities subsequently found more than 4,300 bone fragments and various personal belongings of victims at his residence in Atizapán de Zaragoza.

At the time of his death, Mendoza Celis had accumulated eight criminal convictions, including a life sentence, with total prison terms exceeding 400 years. His medical history included uncontrolled type 2 diabetes, hypertension, tracheal stenosis, and acute bacterial pneumonia, which contributed to his death.
