Piroska Mária Ladányi (1934-1954) was a Hungarian serial killer. She is regarded as one of the most infamous and insidious killers in Hungarian criminal history.
Jancsó-Ladányi and her mother often sexually serviced civilian men and soldiers in return for money, bread, or tallow. At 14, Jancsó-Ladányi had already contracted STDs from her casual encounters.
In the summer of 1953, Jancsó-Ladányi met her first victim, 11-year-old Marika Komáromi. She lured the girl back to her house, where she strangled the child from behind with an electric wire. After strangling the girl, Jancsó-Ladányi undressed the corpse and then rubbed herself against it. She then covered it up with a blanket, tied a noose around the neck and dragged it out of the house before dumping it down a well.
On June 9, 1954, Jancsó-Ladányi came across 13-year-old Piroska Hóppa. Once again, she lured the girl back to the farmhouse where she strangled her. Then, according to her confessions, "[she] looked at the corpse's genitalia, licked it, and then stuck a carrot in her own genitalia, causing her to ejaculate. She then inserted a long broomstick into her vagina. Later, she licked Hóppal's genitalia with her tongue while holding on to her corpse, causing her to ejaculate again". On August 9, 1954, Jancsó-Ladányi strangled 17-year-old Irén Simon after luring her back to the house. Jancsó-Ladányi undressed Simon, but noticed that she was suffering from a venereal disease and refrained from performing any sexual acts with her corpse.She instead dragged the victim's body to the well and dumped it there, before rummaging through her clothes' pockets, stealing 30 forints and then throwing the clothes away.
Two days later, she intercepted 12-year-old Marika Botos at the bus stop. When they reached the farmhouse, Jancsó-Ladányi strangled her with a cotton cord. After satisfying her sexual urges with the little girl's naked body, she dragged it to the well and thew it in. She then hid Botos' clothes under her bed, stealing the 7 forints she had on herself.
On August 14, Jancsó-Ladányi approached her fifth victim, 13-year-old Katóká Szőke, on the railway, luring her to the farmhouse under the pretext of helping carry a package. Jancsó-Ladányi snuck up behind her and strangled her with a trouser strap. She then undressed the body, mutilated it and then threw it into the well, keeping the girl's clothes. She then went to the market, selling her victims' clothes and shoes for 15-20 forints a piece. She got the most out of Hóppal's jacket, shirt and sandals, for which she was paid 45 forints.
On September 2, 1954, at 9 o'clock in the evening, Istvánné Balászi, a 21-year-old resident of Pusztakengyel, reported to the Törökszentmiklós that Jancsó-Ladányi had attempted to rob and then strangle her with a wire. Jancsó-Ladányi was brought in for questioning, but refused to confess. Authorities went to search the farmhouse; police found clothing belonging to the girls that had gone missing in recent months, but were unable to find Balászi's property. One of the officers reported to his superior that he had found a mineshaft with a metal cover on the porch behind the gate. When he opened it, he found a 10-12 meter deep well, supposedly built when the older house had been demolished. They lit up the mine to examine it further, only to find human remains covered in water and mud at the bottom.
Piroska Jancsó-Ladányi was charged with murder and sentenced to death. On December 12, 1954, she was executed by hanging in Szolnok Prison.
