Diego Casanova

Diego Casanova (born 1980) is an Argentine serial killer who murdered six people between 2004 and 2016. Casanova is known as The Prisoner Killer as he murdered five inmates while imprisoned. Additionally, he participated in sixty-seven fights and several riots in prison. Experts describe Casanova as an extremely dangerous prisoner with psychopathic behavior, and one of the cruelest serial killers in Argentine history.

Biography In 1980, Diego Casanova was born in the city of Maipú, Argentina. Casanova began committing robberies at a young age, and became known in his neighborhood as "Gordo Picurú". In 2004, he was briefly arrested for robbery, but released a few weeks later.

In April of 2012, Casanova lost his left eye after another inmate stabbed it with a knife. This earned him the nickname "El Tuerto" ('The One Eyed'). Casanova's behavior behind bars is considered appalling by other inmates and prison staff. Experts have described him as psychopathic and antisocial, which is why he is being medicated with an anxiolytic.

Casanova was sentenced to an additional twelve years in prison for Cruz's murder. During the riot, Casanova killed 35-year-old Darío Vega González, who was serving time for sexual abuse. After the murder, Casanova and the others freed the guards and turned themselves in. Casanova stated that he wanted to attract attention so that he would be transferred to another prison. For the killing, Casanova received another life sentence.

Andrés Florentino Peñaloza Andrés Peñaloza, 17, was serving a sentence for kidnapping and murder. Casanova reportedly reacted indifferently to the murder he committed, caring more about if he would have visitors that day, and that his clothes had been ruined by Peñaloza's blood.

Since the murder of Peñaloza, Casanova has lived in solitary confinement.
