Subsequently, according to the prosecutor's office, he bought at one of the regional enterprises a number of toxic chemicals, including 400 grams of thallium sulfate and sodium azide, which would later be used for the murders.
[6] Solovyov, in a peculiar way, "experimented" with poisons, pouring them in small doses to a number of colleagues at work, who suddenly began to have health problems - aches in joints, hair loss, vomiting and diarrhea.
In the fall of 2006, Solovyov moved to live with Oksana Gurieva, who worked as an acrobatics trainer and had two little daughters.
The very healthy Oksana safely tolerated the poisoning, finding it to be a serious complication of the flu, but her grandmother Taisiya Iosifovna soon died.
The examination found that there was poisoning with salts from heavy metals, and the investigation led to Solovyov, around whom people perished too often for suspicious reasons.
Before the announcement of the verdict, Solovyov expressed remorse for his crimes and said that he would not ask for forgiveness from the victims' families, as he knew he would get none.
[7] On the night of 2 December, Solovyov died in the cell of the pre-trial detention centre, with the forensic medical examination finding that the cause of death was phlegmon - purulent inflammation of the subcutaneous tissues.
