Between 1984 and 1987, he served with the Soviet Border Troops, where he received physical, ideological and combat training, mastering sambo.

After his retirement, with the help of his wife's parents, Chuplinsky founded a chain of shops where he sold wall decorations made from metal.

After that, the bodies of murdered prostitutes were discovered in various desolate areas around Novosibirsk, such as landfills, windbreaks, and hard shoulders of roads.

[3] The victims were beheaded and extensively mutilated, arrows and pentagrams carved on the skin and various amulets were often found near the crime scenes.

In October 2015, a taxi driver named Alexei Ivanov was arrested by investigators who suspected him of being the Novosibirsk Maniac.

When he was asked to give an official testimony, Chuplinsky changed his story, claiming that the young men had unsuccessfully attempted to rob him, and had dropped the phone in the process.

His own co-workers told of rumours that he ran a protection racket centred on sex workers, including in areas where some murders took place.

In 2016, the Investigative Committee began conducting tests using DNA, requesting that all suspects, including Chuplinsky, provide a sample.

During the interrogations, he confessed to killing a total of 29 women; however, on 14 April 2017, he was charged with only 19 counts of murder due to insufficient evidence.

[3] On 28 February 2018, Yevgeny Chuplinsky was found guilty by jury verdict of 19 murders and one theft and sentenced to life imprisonment in a corrective labour colony.
