The first poisoning in Nagyrév took place in 1911; it was not the work of Mrs. Fazekas. The deaths of other husbands, children, and family members soon followed. The poisoning became a fad, and by the mid-1920s, Nagyrév earned the nickname "the murder district." There were an estimated 45–50 murders over the 18 years that Mrs. Fazekas lived in the district. She was the closest thing to a doctor the village had and her cousin was the clerk who filed all the death certificates, allowing the murders to go undetected.
