Nikolai Andreyevich Tymoshenko (; born 1970), known as The Fatinsky Maniac (), is a Belarusian serial killer who killed at least three women in the Mogilev Region from 1999 to 2010. He was found guilty of the respective crimes, and was sentenced to two life terms.

Murders

First known murder

Tymoshenko's first known murder was committed between May and June 1999. During that time frame, he met a young woman aged between 18 and 20 years old in the village of , offering to take her to his dacha to relax and have a drink. The woman offered to pay all expenses, as she reportedly earned 2 million rubles.

After spending some time drinking together, Tymoshenko asked the woman if she could share some of her money with him, to which she categorically refused. Angered, Tymoshenko grabbed her and starting pushing her, causing the woman to hit her head against a nearby wall. She began resisting, causing the assailant to punch her three times in the chest before choking her to death. In order to hide the body, Tymoshenko dismembered the remains and buried them in separate places - one half in his mother's backyard, while the other was buried outside the village. He burned the victim's clothes, passport and personal items, and then spent 900,000 of her money for his own expenses.

Move to Mogilev

Sometime after the first victim's murder, Tymoshenko and his mother moved to Fatina Street in Mogilev, a run-down area of the city occupied by poor people. He made a living by doing odd jobs, most notably butchering pigs at a slaughterhouse, but once his elderly mother passed away, Tymoshenko stopped working overall. Local residents regarded him as a "quiet alcoholic" and loner who spent most of his time drinking and refusing to interact with others at all.

Fatina Street Murders

Around February 17, 2010, Tymoshenko stopped by a local bar to buy wine, where he came across 40-year-old Svetlana Karaseva. After talking for a bit, he invited her over to his apartment so they could drink in private. In a drunken stupor, Karaseva started complaining about her personal issues to Tymoshenko, who attempted to offer her some advice. Irritated, she said that she did not need any help, called him a bum and started swearing at him.

A conflict ensued between the two, during which Tymoshenko knocked her down to the ground and choked her for approximately ten minutes. After making sure that she was dead, he grabbed a knife and then proceeded to dismember, decapitate and disembowel her body. He then put the remains in bags, a bucket, a curtain and Bykova's red jacket, which he then discarded in the wasteland or into the Dnieper. As Karaseva's family members had abandoned her due to her constant drinking and frequent disappearances from home, she was not reported missing.

Less than a month later, Tymoshenko was returning home when a seemingly drunken woman ran up to him and asked him for help, claiming that somebody was chasing her to steal her bottle of vodka. The woman, 35-year-old Svetlana Bykova, had just stolen 20,000 rubles of her own son's money gifted for his birthday, and likely wanted to hide from her relatives. Disintered in asking about her personal life, Tymoshenko nonetheless let her stay.

Upon drinking two glasses of vodka, Bykova started complaining about how all the men in her life were homeless bums. This remark was enough to anger Tymoshenko, who punched her in the temple and strangled her to death. Just like Karaseva before her, Bykova's body was dismembered, decapitated and disemboweled, and then scattered in the nearby wasteland.

Discovery of remains and panic

The recent disappearances of the two women, followed by the unrelated disappearance of a female mortuary worker, sparked fears that a serial killer was operating in Mogilev. On March 23, utility workers found Karaseva's torso, wrapped up in her red jacket, near the Yubileiny-Fatina bridge. Around that time, a husband and wife found a bag containing ribs and a spine, but mistook them for dog meat. The couple took the ribs home, cooked them and ate them, before throwing away the bones on the following morning. In the evening, the couple were visited by policemen, who informed them that the remains they had eaten were actually human.
