Tamara Antonovna Ivanyutina (Russian: Тама́ра Анто́новна Иваню́тина) (née Maslenko, 1941–1990) was a Soviet serial killer who used the extremely toxic poison thallium in her killings. She was the target of a wide-scale investigation in Kyiv during the 1980s.
Biography Tamara Maslenko was born in a large family as one of six children, in which her parents always told her that material security is the main thing in life. Although forensic psychiatric examination recognized Ivanyutina as sane, she was noted as self-centred, vindictive and resentful. During the investigations into the poisonings, it turned out that Ivanyutina had been convicted of speculation, and obtained employment as a dishwasher in a school cafeteria using a fake employment record book because as a former convict, she was banned from work in educational institutions. Chemistry teacher Viktor Stadnik, who suffered from Ivanyutina's actions, noted such traits of her character as "perseverance and arrogance", as well as rudeness and lack of discipline.
Murders Between 17 and 18 March 1987, several pupils and employees of School #16 in the Podilskyi District in Kyiv were hospitalized with signs of food poisoning. Two children – Sergei Panibrat and Andrei Kuzmenko – and two adults died almost immediately, while the remaining 9 people were in intensive care. Doctors initially suspected influenza or an intestinal infection, but some time later, the hair began to fall out from the victims, which is not typical for such diseases. Poisoning was suspected, and a criminal investigation and an investigative team were established. The investigators, after interviewing the survivors, found out that they all felt unwell by having lunch the day before in the school cafeteria, after eating kasha and liver. When the question arose if there was quality control in the school canteen, it was found that a dietitian named Natalia Kukharenko (according to other sources, Kukarenko) had died two weeks before the events, according to official data from a heart disease. However, the circumstances of Kukharenko's death caused doubts among the investigators, and due to this, her body was exhumed. As a result of corresponding studies, traces of thallium were found in corpse tissues. After that, searches were carried out for all persons who had access to the kitchen, including in the house Tamara Ivanyutina lived, who worked as a dishwasher in the dining room of School N#16. During the search, a "small but very heavy jar" was found in Ivanyutina's house. It interested operatives and investigators and was sent for examination afterwards. A laboratory study showed that the can contained Clerici solution – a highly toxic solution based on thallium compounds used in some branches of geology. Ivanyutina was arrested and initially wrote a confession, confessing to the poisoning in the school canteen on 16 March 1987. The reason for the crime, according to Ivanyutina, was that the sixth graders who dined in the dining room refused to set up tables and chairs, and "she decided to punish them". However, she later stated that the confessions were made up from investigators who pressured her, and refused to give further testimony.
Investigation Further investigation of the "Ivanyutina-Maslenko-Matzobory case" showed that Ivanyutina and her family (sister and parents) used thallium for poisoning for 11 years (since 1976); and did not poison as a mercenary goal, but simply because of personal dislikes. The family members purchased the Clerici solution from a friend who worked at a geological institute, explaining to her that the poison was for killing rats. The acquaintance admitted that for 15 years she had given Ivanyutina, her sister and parents a portion of the substance at least nine times. At the beginning of her criminal activities, Ivanyutina poisoned her first husband to get his apartment. After his death, she married a second time, but then poisoned her father-in-law and mother-in-law (who died at an interval of two days), later poisoning her second husband in small portions, to take possession of her husband's parents' house with a plot of land. In September 1986, Ivanyutina got a job as a dishwasher for the school. According to investigators, she needed this work in order to gain access to food and food waste, since she kept a large farm with pigs and chickens. During her time in the dining room, Ivanyutina poisoned (in addition to the previous poisonings) the school party organizer Ekaterina Arsentyevna Scherban, (who died) and the chemistry teacher Stadnik (who survived), who had prevented her from stealing food from the canteen, and two first and fifth grade students (who both survived), who had asked her for the remnants of cutlets for their pets. The investigation proved that Tamara's elder sister, Nina Matzobory, using the same solution, had poisoned her husband and taken possession of their Kyiv apartment. Numerous poisonings were committed by their parents as well: in particular, they killed a neighbour in a communal apartment who was watching television at a loud volume, and a cousin, who made remarks about a toilet. While detained, Maria Maslenko explained her life position to her cellmates: "To achieve what you want, you do not need to write complaints, but to treat everybody as friends. But for especially harmful ones, just add poison to food". The geography of the criminal activities of the family was not limited to Ukraine; it was proven that some of the crimes committed by them in the RSFSR; in particular, her father Anton, while in Tula, poisoned his cousin by mixing poison in her moonshine. Also, members of the family poisoned neighbors' pets.
