In 1971, she and her husband settled in the newly built panel house number 4 on Dimitrov Street.

Fifteen years later, in April 2015, she turned towards the authorities again, this time to the investigative unit of the Fruzensky District in St. Petersburg, giving a statement about her spouse's disappearance.

Samsonova travelled to Pushkin, where she managed to persuade a pharmacist to sell her a prescription drug, phenazepam.

[11] Samsonova later found Ulanova's body lying on the kitchen floor on the night of 23 July and proceeded to dismember it with two knives and a saw.

[4][11] On the evening of 26 July, Ulanova's decapitated body with severed limbs, wrapped in a bathroom curtain,[3] was found near a pond at house number 10 on Dimitrov Street.

The package initially didn't attract any attention for several days, until a local resident took an interest in its contents.

Having entered inside, police officers found traces of blood in the bathroom, and also fastening from the torn-off curtain.

She underwent a forensic psychiatric examination, and on 26 November 2015, the results determined that she was a danger to society and herself, and therefore she was placed in a specialized institution until the end of the investigation.
