Later, in connection with the moratorium on the death penalty imposed by Boris Yeltsin, the verdict was replaced by life imprisonment.

He did not recover from the consequences: he was diagnosed with "an intellectual disability in the degree of moderate debility", after which his mother sent him to a special boarding school, in which Irtyshov was raped.

In 1993 he moved to St. Petersburg, where he got a job as a dishwasher at the "Pegasus" coffeehouse, but his main source of income was homosexual prostitution.

Threatening them with a knife, the criminal took the children to a quiet, secluded place where he raped them, forcing them to drink something from a jar beforehand.

After the act of violence, Irtyshov manually tore apart the boy's perineum, leaving him permanently disabled.

After that, he was treated in a hospital in the United States, with calls for financial help on television for the necessary operation, but despite the fact that the necessary amount of intestines were collected for the organ transplantation, the boy ultimately died.

A month later, having decided that everything had quieted down, Igor returned to St. Petersburg, where on 28 November 1994, he was detained by law enforcement agencies, which by that time had amassed a vast amount of evidence against him.

As a result, the experts identified a number of mental abnormalities, but in general, Irtyshov was declared sane.

Many forensic experts were inclined to believe that soon Irtyshov would begin to purposefully kill his victims, and in addition to rapes, there would be a chain of corpses.

The court found Igor guilty of several articles, including murder, rape, serious bodily harm, and was sentenced to death.
