What this article is about

Infobae reconstructs the extraordinary story of Mario Poggi, a psychologist and criminologist brought into a 1986 Lima police investigation to profile and question Ángel Díaz Balbín. Poggi killed the handcuffed suspect during an interrogation, was sentenced to prison, and years later became a highly visible and eccentric public figure.

Background you need

The article also examines the pressure surrounding the unsolved killings that the press associated with the label 'descuartizador de Lima'. Importantly, Díaz Balbín died without confessing to those killings, and the report states that dismembered bodies continued to appear after his death, making the distinction between suspicion, media labeling and proven responsibility essential.
