From a young age, he exhibited criminal tendencies: having a violent personality and craving alcohol, he repeatedly got into fights with strangers, his colleagues and relatives, leading to multiple detentions by law enforcement.

Although he came to the attention of the police for various offences, including inflicting bodily harm, theft, arson and rape, his guilt could never be proven.

On the night of 30 April 1970, he entered an apartment on Aeroflot Street and attacked the landlady, Ekaterina Kutsevalova, and her daughter Olga with the blunt side of an axe he had brought with him.

He began to rape Ekaterina, believing she was dead, but Olga regained consciousness and started screaming, waking the neighbours and frightening Serebryakov away.

"[5] On the night of 4 to 5 June 1970, Serebryakov committed another brutal crime in a house on Podgornaya Street in the Oktyabrsky District, near Country Park.

On 8 June 1970, Serebryakov was riding a bicycle on a side street near the Airport Highway, when he was noticed by druzhinnik Zagfar Gayfullin.

Serebryakov's fingerprints and blood type matched those of the murderer, and stolen items from the victims were found in his room.

A forensic psychiatric examination determined that Serebryakov did not suffer from mental illness, and although he exhibited clear behavioral deviations, they did not prevent his criminal prosecution.

[7] During the court hearing, the courtroom was packed, with people looking through the windows to see the man who had terrorized the entire city for almost a year and a half.

For their role in apprehending the particularly dangerous criminal, all the militiamen were awarded medals for "Excellent Service in the Protection of Public Order".
