Diego Alexánder Ruiz Restrepo (born 14 March 1990) is a Colombian serial killer active in Chile.
At 22, Ruiz professed the Christian faith, like his family, loved and appreciated by the community of the neighborhood where he lived, in Cali.
[6] According to reports, Ruiz was known for constantly getting involved in conflicts in the neighborhood where he lived, such as arguments, even going so far as to threaten neighbors with a melee weapon.
He was involved in robberies, threats and the use of bladed weapons, which prevented him from obtaining a permanent residence visa in Chile.
[7][8] Several months later on 1 November, Colombian immigrant Carlos Andrés Rivas Angulo (35) was found dead; he emigrated to Chile in 2010.
Little is known about this victim, since he was never married, had no known children, his birth certificate doesn't have the full name of his mother, and his electoral residence did not belong to him.
Despite the fact that she had a residence in Cerro Navia, she was living as homeless in Estación Central area, she suffered from alcoholism and schizophrenia and had two children.
After being stabbed together with his friend Leónidas Vicente Panez, he was kicked by Diego Ruiz, but survived after receiving medical care at the Barros Arana National Institute.
If these 20 deaths are confirmed, Diego Ruiz Restrepo would be considered the most prolific serial killer in the history of Chile.
[7] According to Infobae, chief investigator Pamela Contreras said that the police "realized that it was a subject who was repeating a pattern, who made sequences of walks between sectors that were identical" between the two weeks in which the crimes took place.
[3][16] Ruiz was arrested for investigation on 9 November and days later, a judge ordered him held in custody because he "represented a danger to society."
[19] According to the forensic psychologist, Belisario Valbuena, Ruiz chose this profile because they are "people who are not missed by a family...many of them cannot even be identified.
