Ondrej Rigo (17 December 1955 – 14 June 2022)[1] was a Slovak serial killer and necrophile who targeted women in Bratislava, Munich and Amsterdam from 1990 to 1992.

The last time period he was in police custody in Czechoslovakia was from 28 September 1989 to 9 December 1989, because of unauthorised leaving of the Republic, which was illegal under communist rule.

After the fall of the Iron Curtain and the end of communism in Czechoslovakia, people were allowed once again to travel freely in Europe; Rigo then continued with his crimes abroad.

On 9 December 1989, the same day he was released from prison (and three weeks after the start of the Velvet Revolution), he travelled to Vienna without any valid passport.

After his release from prison, Rigo escaped from a refugee camp and travelled to Munich, where he continued his burglaries and started his killing spree.

"He killed her and got aroused sexually," recalled Anton Heretik, author of Rigo's psychological evaluation during the investigation.

Rigo smashed her head with a 2.5-kilogram metal pipe, wrapped the upper part of her body in a blanket, and raped her corpse.

On the night between 31 July and 1 August 1990, Rigo snuck through the partially open balcony door and into the Munich apartment of Ilka Z.

Afterwards, he covered up the body and searched the house for valuables, finding a golden necklace and an unknown amount of German marks, which he stole.

During the night of 27 September 1990, Rigo snuck into her ground-floor apartment through a partially open balcony window and killed her with a stone weighing over 5.5 kilograms (probably a pavement cobblestone).

Underneath the balcony, the police found some Dutch coins and cigarette butts with Rigo's DNA on them.

On 3 January 1991, early in the morning, the bodies of Anna P. (40) and her son Juraj N. (aged 14–16) were found inside a ground-floor flat in a dormitory at an unspecified location in Bratislava.

Jana B. noticed that Rigo's light-blue pants were hand-sewn in the crotch area, which later helped in identifying him.

That same night, before attacking Jana B., Rigo entered through a different window in the neighbourhood, but it led only to a small, locked storage room.

Three months after his last kill and after the attack on Jana B., he murdered Helena N. (79) near Záhradnícka Street in Bratislava.

Rigo removed a net from the kitchen window of this ground-floor apartment, killing Helena N. with a piece of concrete.

There were traces of blood on his shoes and trousers and inside his locker there were jewels belonging to the victim.Ondrej Rigo was arrested by the Slovak criminal police on 4 March 1992, only hours after his last murder.

Later, he would claim that the blood on him was syrup and that his sperm found on the victim was arranged by a prostitute from an erotic club.

He explained his footprints beneath the balconies and cigarette butts by claiming he was there by chance and had to urinate or that he was curious and took a look through some windows.

Ondrej Rigo was sentenced on 7 December 1994[4] by the City Court of Bratislava after a trial that lasted ten days.

[5] A senate headed by Peter Šamko sentenced him to life imprisonment in the "third class", which means highest security prison in Slovakia.

[6] During his finishing speech, the representative of the General Prosecutor's Office of Slovakia, Ivan Segeš, proposed to confirm the life imprisonment sentence because Rigo's guilt had been proven once again in the appeal process.

On 28 February 1996,[7] the senate of the Highest Court of Slovak Republic denied Rigo's appeal and confirmed his sentence.

He is a combination of schizoid and antisocial psychopath, creating a very dangerous type of criminal", claims Heretik.

[8] According to his psychological profile, the strangeness, lack of hospitality and language barrier in a foreign country could have influenced his later behaviour.

At first I thought I'm dreaming, because I was living alone but when I received another hit to the head I woke up and the wooden shaft from a hoe Rigo stole outside, on the building's yard, broke, because it was moldy," she recalls.

He then quickly fled the apartment while Jana B. alarmed her neighbour by banging on the wall, instructing him to call the police.

The neighbour told the police he heard some weird noises but he thought Jana B. was probably framing pictures in the middle of the night.

's mother, the worst thing was that Rigo was caught over a year after the attack on her daughter, all the time knowing he might come back to finish the job.

I don't want to talk about him, read about him or know anything about him.Jana B. stayed in the flat she was attacked in for a long time, not feeling the need to move.
