All of the attacks were done at night and against food vendors, whom Ageyev struck with a metal adjustable wrench he carried with him at all times.
[2] Acting in a similar manner, on 10 September, Ageyev attacked the vendor of the "Cigarettes" kiosk on Molodogvardeitsev Street, hitting her on the head at least 4 times.
[3] By mid-September, as the search for the then-unknown serial robber was intensifying across Chelyabinsk, he was eventually identified as the prime suspect.
His new acquaintance offered him a drink, to which he agreed, after which they bought a bottle of vodka in the store and went to the man's apartment, located in a five-storey building on Aluminievaya Street.
After making sure that he was knocked unconscious, Ageyev proceeded to sexually abuse the 10-year-old girl for a prolonged period of time.
[5] Having completed the rape, Ageyev took the girl to the bathroom and threw her into the bathtub, put the water on and forcibly held her head underwater until she drowned.
Unbeknownst to him, the man he had assaulted survived the injuries, and once his wife returned in the morning, she immediately notified the authorities and an ambulance.
After analyzing the surveillance footage taken from the store he and the man had bought the bottle of vodka in, he was quickly identified as the prime suspect and put on a wanted list.
Two days later, law enforcement officers detained Ageyev at a railway station in Chelyabinsk and he was transported back to Yekaterinburg.
1, he spontaneously confessed to the two murders and the other crimes he had committed - because of this, the case was handed over to Mikhail Borodin, the head of the Sverdlovsk Oblast's Main Directorate of the Ministry of Internal Affairs.
[11] Because of this, on 20 April, Ageyev grabbed a piece of cement and struck his cellmate while he was lying down, hitting the man approximately 39 times.
[11] In the subsequent investigation, Ageyev admitted that he killed the man because he simply disliked him, and said that he got the piece of cement from somewhere within the colony shortly before the actual murder.
