Who Was A. Cikatila?
Andrei Chikatila is considered the most famous Russian serial killer of all time.
He killed several dozen people between 1978 and 1990.
The madman of his victims lurked at bus stops or at the train station, lured them into the forest offering them money or drugs, killed them and disgusted their bodies.
When questioning witnesses near the place where the manic victim Svetlana Korostik was last seen, local police officer Vladimir Glikin arrested Chikatila.
The man confessed to having killed 56 people, but an estimated 36 other people were victims of him.
In 1994 A. Čikatila was executed.
Incidentally, 2014 A dishonored body of nineteen-year-old Mary Glikina was found in Novgorod, Russia. Investigators believed the murder could be related to the fact that his father, V. Glikin, arrested A. Čikatila.
The killer was saved by a genetic trait.
The article on Slate.fr states that Andrei Chikatila had many nicknames. He was called the Rostov Butcher, Rostov Man, Rostov Butcher, or Rostov Monster.
For a long time, as Pierre Lorraine wrote in his book The Rostov Monster, which analyzes crime during the collapse of the Soviet Union, the Soviet Union refused to acknowledge that one man committed dozens of murders because it was impossible in socialist society to a serial killer occurred.
When A.Cikatila’s crimes were finally recognized, nearly half a million identity checks and over 150,000 were carried out in the country over several decades. blood test. The goal of these efforts is to find a match for the dried sperm found at a crime scene.
Slate.fr. He writes that A.Cikatila’s case is so amazing too because this man’s blood was also examined, but the results were negative.
As the testimonies against him began to multiply and his guilt was no longer in doubt, further blood tests were conducted that showed that the killer had a very rare characteristic: his sperm and blood cells had a different histocompatibility as if they belonged to two different people. Due to this atypical genetic inheritance, A.Cikatila managed to escape for a long time.
What did the mathematician who studied the killer’s actions see?
In 2012, two scientists published the results of their research on the “Butcher of Rostov”. Two professors from the University of California, Los Angeles, Ph.D. Mikhail V. Simkin and Ph.D. in Electrical Engineering Vwani Roychowdhury, analyzed the chronology of the A. Chikatila murders.
They investigated 12 years of murder crimes (from 1978 until his arrest in 1990) and 53 murders committed by him.
Scientists’ first observation: After compiling the graph of the number of murders committed by A.Cikatila, they obtained a curve called “Kantor’s Stairs” (named after the 19th century German mathematician Georg Kantor), also sometimes called. .. “cursed stairs”.
“This uneven curve corresponds to a function that is not constant, but has a derivative of zero at almost all points. In G. Kantor’s theory, the values range from 0 to 1, but the two researchers simply redistributed the scale, so the curve increased from 0 to 53, “explains Th.Messias, the paper’s author.
The case of A. Cikatila is so amazing too because this man’s blood was also examined, but the results were negative.
The first curve, which could be called “Chicatila Stairs”, has two horizontal segments from 1983-1987. period. Both are longer than the others.
The researchers did not write in their study that a segment corresponds to A.Cikatila’s first arrest, during which she was unable to unmask him, but the arrest halted the killer’s attacks. Investigators also did not notice that the second segment coincided with a period when the press began actively writing about the mysterious murders that took place in the Rostov region. This apparently also forced A. Čikatilas to calm down for a while.
The graph shows how a pattern appears on a regular basis: several small steps are very close to each other until a new threshold reappears. According to this analysis, each threshold corresponds to a period in which an assassin, saturated with his previous crimes, still does not feel the need to restart, he needs to be mature for it before feeling the need to kill again.
The researchers point out that the killer should not be expected to commit murder when his nervous arousal exceeds a certain level. According to them, the offender needs time to plan and prepare for another crime.
M. V. Simkin and V. Roychowdhury were able to model the temporal distribution of A. Čikatila’s crimes. They clarified the mathematical relationships between the frequency of homicides and their number. In other words, the frequency of A. Cikatila crimes has decreased very slowly over time.
M. Simkin and V. Roychowdhury concluded that the desire to kill A. Chikatila originated at the neural level. They had the idea to compare the data related to the crimes of A. Čikatila with the data of patients with epilepsy and to compare the crimes of A.Čikatila and the seizures of patients with epilepsy.
These scientists were not the first to do so, as early as 1887. Professor Cesare Lombroso, founder of the Italian School of Criminology, described this in his book, The Criminal Man, which is subtitled as a criminal by nature, a madman, an epileptic. .
Enthusiastic about the study of epilepsy, Lombroso had previously published a book, Genius and Madness, in which he wrote about the connection between genius and madness and drew a clear and reasoned parallel between epilepsy and inspiration in art and science. According to C. Lombro, crime and art are very close, just one step between them.
Slate.fr writes that the brains of criminals, creative professionals or epileptics gradually accumulate information related to nerve impulses, which eventually leads to unexpected consequences. Like a drop of water, ultimately, but unexpectedly overflows the container when no one expects it.
“The enthusiasm of MV Simkin and V. Roychowdhury is beyond question, as is part of the frustration caused by their research. In their work, both scientists explain that they lack very important information. A. Cikatila, despite their Activity in the commission of crimes probably also failed, and some unforeseen events forced him to suppress his murderous instinct for a time. Scientists say they could analyze the trajectory of the murderer’s actions much more deeply if they had information about his failures.
Until now, their hypothesis is that the failed murders could quickly provoke new attempts for the murderer to satisfy his need or calm frustration. However, due to lack of data, scientists cannot draw any conclusions, “writes Th. Messias.
