[edit]Victims

Tialda Visser, 12 years old, was reported missing on 11 May 1979, after she didn't return home after ballet classes at the Royal Conservatory of The Hague. Four days later, on 15 May, her lifeless body was found near the Leeghwaterbrug in The Hague. The cause of death could not be determined.

Emy den Boer, 18 years old, disappeared on 3 April 1980. She left her home in Schiedam to go to the Academie voor Lichamelijke Opvoeding in The Hague, however she never got there. Two days later, on 5 April, her body was found by a hiker in the forrest nearNistelrode. She was shot in the stomach and head.

Edith Post, 11 years old, disappeared while at school on 29 September 1980. She left her class to get some materials from a closet in the hallway but didn't return. On 2 October her body was found in the dunes of Wassenaar. She was beaten to death, probably with a branch that was found next to the body.

[edit]Arrest
After the murder on Edith Post, the police received an anonymous call with the information that Edith had bitten her murderer, and a bouncer of nightclub "De Nachtegaal" (The Nightingale) had a severe bite wound in his pink. The bouncer was arrested and turned out to be Koos Hertogs. Police investigated his house and found bloodtraces of Tialda Visse and Emy den Boer. On the attic police found an isolated room. It is believed that Hertogs hid and raped his victims here for a period of time, before killing them. Koos Hertogs got sentenced to life imprisonment. Until 1989 Hertogs denied killing the girls. However after consultation with his lawyer he confessed so he could be placed in a lighter regime.
[edit]Sting operation
For a long time there were rumours that Hertogs had protection from higher hand. In the book Zuidwal, that tells the story of the serial killer, it is claimed that Hertogs got protected by Cornelis Stolk. An important judge and vicepresident of the court. However both men denied the claims. In 2009 crime reporter Peter R. de Vries started a sting operation, trying to reveal if Hertogs murdered more people or if the claims made in the book were true. While being filmed with hidden camera's Hertogs, talking with a 'dear' friend, who turned out to be an infiltrant working voor De Vries, made some notable claims.

He admitted he kidnapped and murdered the three girls.
With the murder on Edith Post he had an accomplice.
Three times he had plans to murder someone, however the plans weren't carried out or failed.
- A man he had an argument with fled inside a poolhall before Hertogs could kill him.
- The director of a juvenile prison, however the man already died before Hertogs could carry out his plan.
- An fellow inmate was lured into a trap, however a guard got suspicious and locked him up.
Confessed knowing who murdered the two Swedish women, Gun-Ingeborg Johannesson (18) and Ann Jönsson (19), in a forrest nearLa Roche-en-Ardenne.
Confessed he had a special bond with judge Cornelis Stolk. Stolk paid for the driver's license of Hertogs and after an earlier conviction Stolk placed him under the care of as 'befriended' psychiatrist, who later turned out to be the ex-wife of Stolk. In the end of the televisionshow it was revealed that Hertogs, in return, offered sexual services (oral sex) and childpornagraphy to Cornelis Stolk.
