Artyom Grabovoi

Artyom Viktorovich Grabovoi (Russian: Артём Викторович Грабовой; 1983 – February 9, 2014), known as The Knyaze–Volkonskoye Maniac (Russian: Маньяк из Князе-Волконского), was a Russian military officer, serial killer and rapist responsible for the murders of two women and one girl in the village of Knyaze–Volkonskoye, Khabarovsk Krai between January and February 2014. He was never arrested for the crimes, as he hanged himself upon learning that he was being investigated, with his guilt definitely proven post-mortem and the case officially closed.

On January 1, 2014, Grabovoi travelled to nearby Khabarovsk, where he spotted a 15-year-old girl at a bus stop. He invited her into his SUV, ostensibly to drive her to her desired destination, which was recorded on CCTV footage from a nearby surveillance camera. Two days later, the girl's partially naked body was found on a rural road, near the cemetery in Chyornaya Rechka. A forensic autopsy determined that she had died of hypothermia, but had also been raped by an unknown third party prior to her death, whom likely left her to die in the cold.

Little is known about Grabovoi's early life. Born in 1983 in the village of Bolshoi Atmas, Omsk Oblast, he is known to have graduated the Omsk Higher Tank Engineering School, have married and had a daughter sometime during the 2010s. As part of his military duty, he was stationed at a garrison located in Knyaze–Volkonskoye, where he lived in an apartment provided by the army. Around 2013, following a heated scandal with his wife, whom Grabovoi threatened to kill with his hunting rifle, the woman left him. Following her departure, Grabovoi moved in with a female acquaintance in another part of the village, using her burgundy-colored Suzuki Grand Vitara to travel around, since she did not use it often and he himself had no means of transportation.
