“I didn’t miss this one,” was one of the confessions made by John Ferney Cano, according to one of his sisters, before murdering the doctor and urologist Juan Guillermo Aristizábal in Medellín.
The case caused terror in the El Poblado sector, on April 18, on the ninth floor of the Medellín Clinic, where Juan Guillermo Aristizábal was murdered.
John Ferney Cano, In addition, he set fire to the office where he was treated for several years and minutes later, amidst the screams of the Police, He took his life in a bathroom.
Marcela Cano, John’s sister, broke the silence and decided to tell her version of the events. “He even told me ‘I won’t pass this one’, But you wouldn’t think he would do something like that,” he said.
Marcela refers to the crime and to a text that they found on her brother’s computer, titled Memoir of a Sensitive Madman, 362 pages.
“We didn’t know the half of what he was suffering, the pain he felt, because one must be very desperate to do something like what he did and not only that, he left the evidence. “I say that this has to be of some use, that doctors work by vocation, not for money,” said the woman.
John’s extensive story details that for nine years he had been feeling pain in the upper part of his penis, which is why he went to the office of urologist Juan Guillermo Aristizábal three years ago.
“That procedure that they did did not take away the pain, Before, it affected him more, because it was no longer just the pain he had, it was also dealing with the circumcision that bled and brought out pus. One doesn’t know that, but it was poorly made,” Marcela said.
John Ferney Cano He made clear in his writing the disappointment he felt with the doctor’s procedure.
“I have decided that the individual who vilely mutilated my penis must die. For me he is a traitor, a swindler, a mediocre, a freeloader, a torturer and a mutilator who represents the figure of my executioner. “It is a monster, an animal that must be hunted, a demon that must be executed without mercy and I have to personally take care of it.” reads on one of the pages of John’s book.
Although they never suspected that this would happen, the family reveals that there was a key moment in this story in September 2023.
“Due to so many obstacles… The last time he went to the doctor, all he did was laugh, he said he didn’t care.. I think that was the triggerbecause my brother no longer had money,” said Marcela Cano.
Those who did know what was happening They were the friends, family and co-workers of the urologist Juan Guillermo Aristizábal, since the name had already threatened the doctor and the complaint had been made at the time.
Noticias Caracol consulted the Prosecutor’s Office about these threats, but There was no answer about the protocol to protect the doctor’s life.
Doctors in the department are on alert with what happened. “Patients do not want to bear the frustration of the doctor’s failure, as if we were gods or infallible beings. Every doctor is a human being capable of making mistakes and even failing,” said Carlos Valdiviezo, president of the Medical College of Antioquia.
Juan Camilo Arango, doctor and friend of the murdered urologist, agrees with this. “We doctors have been placed on a level of gods and we are not gods, We are human beings and medicine is not science, medicine is an art of interpreting signs and symptoms. that are different in each human being,” he said.
How did John confess that he was going to murder the doctor?
Memoir of a Sensitive Madman ends with a February 29, 2024 letter from John Ferney, addressed to one of his six brothers, where he directly acknowledges that he would attack the doctor.
“Dear brother, Fate has given me the possibility of punishing by my own hand to whom for a few miserable pesos he dared to seriously injure me. I have pondered this decision for quite some time. and I have come to the conclusion that I need to do this to feel good about myself,” reads the text from the author of the crime.
This crime, according to the Prosecutor’s Office, could prescribe, since that John Ferney, the protagonist of the story, also died.
