Editing Andrei Chikatilo (section)

==First arrest and release==
On 13 September 1984, Chikatilo was observed by two undercover detectives attempting to talk to young women at a Rostov bus station. The detectives followed him as he wandered through the city, trying to approach women and committing acts of [[frotteurism]] in public places.{{sfn|Conradi|1992|p=1}} Upon Chikatilo's arrival at the city's central market he was arrested and held. A search of his belongings revealed a knife with a {{convert|20|cm|adj=on}} blade, several lengths of rope, and a jar of [[Vaseline]].{{sfn|Ramsland|2011|p=137}} He was also discovered to be under investigation for minor theft at one of his former employers, which gave the investigators the legal right to hold him for a prolonged period of time.{{sfn|Berry-Dee|2011|p=307}} Chikatilo's dubious background was uncovered, and his physical description matched the description of the man seen walking alongside Dmitry Ptashnikov prior to the boy's murder. A sample of Chikatilo's blood was taken, the results of which revealed his [[ABO blood group system|blood group]] to be type A,{{sfn|Cullen|1994|p=87}} whereas semen samples found upon a total of six victims murdered by the unknown killer throughout the spring and summer of 1984{{sfn|Cullen|1994|p=78}} had been classified by medical examiners as being type AB.{{sfn|Fido|1995|p=121}} Chikatilo's name was added to the card index file used by investigators; however, the results of his blood type analysis largely discounted him as being the unknown killer.{{refn|group=n|By Chikatilo's arrest, this index file had expanded to include over 25,000 individuals investigated in connection with the murders.{{sfn|Krivich|1993|p=100}}}}

Chikatilo was found guilty of theft of property from his previous employer.{{sfn|Conradi|1992|p=118}} His membership of the Communist Party was revoked and he was sentenced to one year in prison.{{sfn|Krivich|1993|p=206}} He was released from custody on 12 December 1984 after serving three months.{{sfn|Conradi|1992|p=118}}<ref>{{cite news|url=https://newspaperarchive.com/us/virginia/winchester/winchester-star/1992/10-15/page-7|title=Worst Serial Killer Gets Death Sentence|newspaper=[[The Winchester Star]]|agency=[[Associated Press]]|page=A7|date=15 October 1992|access-date=4 May 2025}}</ref> On 8 October 1984, the head of the Russian Public Prosecutors Office formally linked twenty-three of Chikatilo's murders into one case and dropped all charges against the mentally disabled youths who had previously confessed to the murders.{{sfn|Conradi|1992|pp=112–113}}

===Further murders===
Upon his release from prison in December 1984, Chikatilo found new work within the supply department of a locomotive factory in Novocherkassk and kept a low profile. He did not kill again until 1 August 1985{{sfn|Krivich|1993|p=216}} when, on a business trip to Moscow, he encountered an 18-year-old woman, named Natalia Pokhlistova, standing on a railway platform near [[Domodedovo Airport]]. Pokhlistova was lured off a train into a thicket of woods close to the village of Vostryakovo where she was bound, stabbed thirty-eight times in her neck and chest, then strangled to death.{{sfn|Krivich|1993|pp=217–218}}

Based upon the hypothesis that the killer had travelled from the Rostov Oblast to Moscow via air, investigators checked all [[Aeroflot]] flight records of passengers who had commuted between Moscow and the Rostov region between late July and early August. On this occasion, however, Chikatilo had travelled to Moscow by train and, accordingly, no documentation existed for investigators to research. Four weeks later, on 27 August, Chikatilo killed another young woman, Irina Gulyaeva, in Shakhty. As had been the case with Pokhlistova, the wounds inflicted upon the victim linked her murder to the hunt for the serial killer.{{sfn|Cullen|1994|p=111}}

In November 1985, a special procurator, [[Issa Kostoyev]], was appointed to supervise the investigation, which had by this stage expanded to include fifteen procurators and twenty-nine detectives assigned to work exclusively upon the [[Manhunt (law enforcement)|manhunt]].{{sfn|Cullen|1994|p=120}} The known murders linked to the manhunt were carefully re-investigated, and police began another round of questioning of known sex offenders and homosexuals. The following month, the ''[[militsiya]]'' resumed the patrolling of railway stations around Rostov, and [[Undercover operation#Plainclothes law enforcement|plain clothed]] female officers were ordered to loiter around bus and train stations.

At the request of Burakov, police also took the step of consulting a [[psychiatrist]], Dr. Alexandr Bukhanovsky,{{sfn|Ramsland|2011|p=135}} the first such consultation in a serial killer investigation in the Soviet Union.{{sfn|Cullen|1994|pp=125–126}} All crime scene and medical examiner's reports were made available to Bukhanovsky, upon the understanding he would produce a [[offender profiling|psychological profile]] of the unknown murderer for investigators.<ref>{{cite news|last=Meek|first=James|url=https://www.newspapers.com/clip/100030100/the-observer/|title=Rostov Ripper Casts a Shadow over Russia|newspaper=[[The Observer]]|date=26 January 1997|access-date=9 July 2022}}</ref>
