Rigo was known as a serial killer and necrophile. From 1990 to 1992, he attacked mainly older and lonely women in Bratislava, but also in Munich and Amsterdam.
He broke into the apartments through the windows and killed the sleeping victims with blows to the head. He subsequently fucked their corpses.
He was detained several hours after the last murder in Bratislava. Police had irrefutable evidence and DNA samples, but Rigo never confessed.
After serving 25 years in prison, Rigo applied for parole in 2018 due to ill health, but the court did not comply.
He was supposed to have heart problems and spent some time in the hospital. The exact cause of his death has not been announced.
Rigo was born on December 17, 1955 in the town of Modra in western Slovakia. At the age of fourteen, he went to a re-education correctional facility and later traveled with his siblings to an orphanage.
Ondrej Rigo died in prison on June 14, 2022 at the age of 66.
