Yevgeny Alexandrovich Chuplinsky was born on 14 March 1965 in Novosibirsk, Russia. His early life is not well-documented, but he graduated from school with average grades. In 1981, he enrolled in a mechanical engineering college. While studying there, he was an active member of the Komsomol, a communist youth organization.

After completing his education, Yevgeny served in the Soviet Border Troops from 1984 to 1987. During this time, he received training in physical fitness, ideology, and combat skills, particularly in the martial art of sambo. He became known among his colleagues for his tendency to seek approval from superiors, which led to a reputation as a hypocrite.

After his military service, he joined the police force, eventually rising to the rank of sergeant. Yevgeny began his career as a security guard in the Kirovsky District and was later transferred to the Leninsky District in 2000. By 2003, he retired from the police with a medal for his distinguished service, along with numerous letters of gratitude from his employers.

Following his retirement, Yevgeny started a business with support from his wife's parents. He opened a chain of shops that sold metal wall decorations. Throughout his life, Yevgeny married three times and had two children. He was known to support the United Russia party, which is led by Vladimir Putin.

In 1998, Yevgeny Alexandrovich Chuplinsky became a taxi driver after buying a Lada Samara. In November of that year, he committed his first murder. Soon after, bodies of murdered sex workers began to appear in desolate places around Novosibirsk, including landfills and the sides of roads. The victims were often severely mutilated and beheaded. Investigators found markings like arrows and pentagrams carved into some of the victims' skin.

There was debate among officials about whether these markings had a ritual purpose or were intended to confuse law enforcement. Chuplinsky did not hide the bodies, leaving them in locations where they were easily found. Due to the extreme disfigurement of the victims, some were never identified.

Initially, police treated the cases as separate incidents. However, by the mid-2000s, it became clear these murders were the work of a single serial killer. The investigation did not lead to immediate results, as the identifications of witnesses were inconsistent. The murders ceased around 2005, leading investigators to wonder if the killer was imprisoned or dead.

In 2016, Chuplinsky became a suspect after a woman disappeared, and her mobile phone was linked to him. Although he changed his story about how he obtained the phone, he was released due to insufficient evidence. As investigations continued, more circumstantial evidence pointed to him, including testimonies from sex workers who claimed he ran a protection racket in their circles. Chuplinsky was arrested but released again due to a lack of concrete evidence.

In 2016, DNA tests linked him directly to multiple crime scenes. He was arrested on April 23, 2016, and charged with 17 murders. After a psychological evaluation, he confessed to killing 29 women. However, he later recanted this confession. Following extensive interviews with witnesses, he was charged with 19 murders in early 2017.

On February 28, 2018, he was found guilty of 19 murders and one theft, receiving a life sentence. However, the verdict was contested due to some charges exceeding the statute of limitations. By November 2018, he was retried and again sentenced to life. As of September 2019, he is serving his sentence at the Snezhinka Labor Colony in Khabarovsk Krai.
