Editing Andrei Chikatilo (section)

==Psychological profile==
Bukhanovsky's 65-page psychological profile described the killer as a reclusive man aged between 45 and 50 years who had endured a painful and isolated childhood, and who was incapable of [[flirting]] or courtship with women. This individual was well educated,<ref>{{cite news|last=Matthews|first=Owen|url=https://www.themoscowtimes.com/archive/a-killers-confidante-in-a-murderous-town|title=A Killer's Confidante in a Murderous Town|newspaper=[[The Moscow Times]]|date=30 January 1999|access-date=26 March 2021}}</ref> likely to be married and to have fathered children, but also a [[Sadistic personality disorder|sadist]] who suffered from impotence and could achieve sexual arousal and release only by seeing his victims suffer. The murders themselves were an analogue to the sexual intercourse this individual was incapable of performing, and his knife became a substitute for a penis which failed to function normally.{{sfn|Cullen|1994|pp=127–129}} Because many of the killings had occurred on weekdays near mass transport hubs and across the entire Rostov Oblast, Bukhanovsky also argued that the killer's work required him to travel regularly, and based upon the actual days of the week when the killings had occurred, the killer was most likely tied to a production schedule.{{sfn|Cullen|1994|p=129}}

Chikatilo followed the investigation carefully, reading newspaper reports about the manhunt for the killer which had begun to appear in the press{{sfn|Cullen|1994|p=233}}<ref>{{cite web|last=Sloane|first=Wendy|url=https://apnews.com/article/98473676526672d6f73b81e27174fb84|title=Court Convicts Former Teacher of Mass Murder|work=[[Associated Press]]|date=14 October 1992|access-date=21 January 2022}}</ref> and keeping his homicidal urges under control.<ref>{{cite news|first=Wendy|last=Sloane|url=https://www.newspapers.com/clip/31595493/the-philadelphia-inquirer/|title=Russian Man Convicted of 52 Murders|newspaper=[[The Philadelphia Inquirer]]|date=15 October 1992|access-date=16 October 2021}}</ref> For almost a year following the August 1985 murder of Gulyaeva, no further victims were found in either the Rostov or [[Moscow Oblast]]s whose bodies bore the signature mutilations of the unknown murderer. Investigators did tentatively link the murder of a 33-year-old woman named Lyubov Golovakha—found stabbed to death in the [[Myasnikovsky District]] of Rostov on 23 July 1986—to the investigation, although this was solely upon the basis that the killer's semen type matched that of the killer they were seeking, that the victim had been stripped naked prior to her murder, and that she had been stabbed in excess of twenty times. The victim had not been [[dismemberment|dismembered]] or otherwise mutilated, nor had she been seen near mass transportation. Because of these discrepancies, many investigators expressed serious doubts as to whether Golovakha's murder had been committed by the killer they were seeking.{{sfn|Cullen|1994|pp=133–135}}

===Investigative theories===
On 18 August 1986, a victim was found buried in a depression of earth in the grounds of a collective farm in the city of [[Bataysk]]. The wounds inflicted on this victim bore the trademark mutilations of victims linked to the manhunt killed between 1982 and 1985. The victim was an 18-year-old court secretary named Irina Pogoryelova. Her body had been slit open from the neck to the genitalia, with one breast removed and her eyes cut out. As the murderer had made serious efforts to bury the body, some investigators theorized that this explained the sudden dearth in the number of victims found.{{sfn|Cullen|1994|p=136}}

As the victims killed in the Rostov Oblast in 1985 and 1986 had died in the months of July and August, by the autumn of 1986, some investigators gave credence to the possibility that the perpetrator had relocated to another part of the Soviet Union and was returning to the Rostov Oblast only in summer. The Rostov police compiled bulletins to be sent to all forces throughout the Soviet Union, describing the pattern of wounds their unknown killer inflicted upon his victims and requesting feedback from any police force who had discovered murder victims with wounds matching those upon the victims found in the Rostov Oblast. The response was negative.{{sfn|Conradi|1992|p=115}}{{refn|group=n|Uzbek investigators did not link the two murders committed by Chikatilo in Tashkent to the series because in one instance, the victim had been beheaded,{{sfn|Conradi|1992|p=95}} and in the second instance, the mutilations upon the victim had been so extensive police had concluded the body had been caught in a [[mechanised agriculture|harvesting machine]].{{sfn|Krivich|1993|p=225}}<ref>{{cite news|url=https://news.google.com/newspapers?nid=1290&dat=19921015&id=jeg0AAAAIBAJ&pg=3807,7156775&hl=en/|title=Caged Russian Grandfather Guilty of 52 Grisly Murders|newspaper=[[Boca Raton News]]|agency=[[Associated Press]]|date=15 October 1992|access-date=18 July 2016}}</ref>}}

===1987===
In 1987, Chikatilo killed three times. On each occasion, the murder took place while he was on a business trip far away from the Rostov Oblast, and none of these murders were linked to the manhunt in Rostov.{{sfn|Conradi|1992|p=133}} Chikatilo's first murder in 1987 was committed on 16 May, when he encountered a 12-year-old boy, Oleg Makarenkov, at a train station in the Urals town of [[Revda, Sverdlovsk Oblast|Revda]]. Makarenkov was lured from the station with the promise of sharing a meal with Chikatilo at his [[dacha]]; he was murdered in woodland close to the station, although his body remained undiscovered until 1991.{{sfn|Conradi|1992|p=212}} In July, he killed a 12-year-old boy, Ivan Bilovetsky, in the Ukrainian city of [[Zaporizhia]],{{sfn|Cavendish|1996|p=25}} and on 15 September, he killed a 16-year-old vocational school student, Yuri Tereshonok, in woodland on the outskirts of [[Saint Petersburg|Leningrad]].{{sfn|Krivich|1993|p=221}}
