Three men killed 28 people in Belgium between 1982 and 1985. The police knew they used special forces ammunition, stolen prototype body armour, and gendarmerie tactics. The case is now closed.
I went down this rabbit hole for a project I was working on and the more I read about it the harder it gets to call it an unsolved case. Unsolved suggests they tried.
This took place in November of 1985. The Van de Steen family, two parents and two children, finish their Saturday shopping at a Delhaize supermarket on Parklaan in Aalst, which is a small Flemish town about an hour west of Brussels. It is the long weekend of Saint-Martins Day, the children's festival in Flanders, and the parking lot is full of families doing exactly the same thing as the Van de Steens. They walk back to their car at around 7:30pm. Gilbert, the father in front with Rebecca, ten years old. Thérèse, the mother, a step behind, holding nine year old Davids hand.
Three men get out of a Volkswagen Golf. Dark clothes, balaclavas, and theatrical face paint smeared over the balaclavas. They open fire in the parking lot before they get to the supermarket doors.
Rebecca sees them raise their shotguns at her father and shouts at them. Her exact words were "dont shoot, thats my dad." She did not realise she was trying to negotiate with three men who walked into a Belgian supermarket parking lot to murder strangers for sport. They shoot Gilbert first, then Rebecca. Thérèse, still holding Davids hand, tells him to run. Then they shoot her.
David runs into the supermarket and hides by the comic strip rack. One of the gunmen finds him there. In the book David wrote about this 25 years later, he says the man looked down at him, grinned, and shot. Nine bullets at a nine year old. But David survived. He is the only member of his family who did.
Inside the Delhaize the killing continued. Witnesses said the gunmen were laughing while they shot people. Roaring at customers on the floor. Enjoying it apparently. The whole attack lasted about fifteen minutes. The total cash they took from the supermarket was less than 18,000 euros. Eight people died that night and nine more were wounded.
Then the gang walked out. The leader, the tall one police would later call the "Giant", walked calmly alongside the moving Volkswagen and climbed in through the rear hatch while the car was still in motion. An armed gendarmerie patrol that had been checking the parking lot every twenty minutes that night pulled away from the lot about fifteen seconds before the first shot was fired. Three municipal police vehicles in the area tried to start their engines when the gunfire started and could not. One police van pursued the Volkswagen for a few kilometers and then lost it.
The men who killed Gilbert and Thérèse and Rebecca Van de Steen and five other people that night drove west and were never seen again.
Aalst was their eighth attack. Between March of 1982 and November of 1985 the same three men killed 28 people across Belgium. Supermarkets, restaurants, a textile factory, a gun shop. The first wave from 1982 to 1983 was about money. The second wave in 1985 wasnt about money anymore. Three Delhaize supermarkets in six weeks, twenty-six dead total in the four 1985 attacks. Then they stopped forever.
The buckshot loaded in their shotguns was a rare type used by Group Diane, which was a Belgian gendarmerie special forces unit. Some of the police officers who exchanged fire with them at earlier robberies said the gang was using gunfight tactics that were taught in Belgian police academies. The Volkswagens were modified by someone with mechanic grade facilities. The bulletproof vests they wore had been stolen from a textile factory in Temse before that factory's contract to manufacture vests for the Belgian police was public information.
In 1986, a year after they stopped, divers searched a stretch of the Brussels Charleroi canal at a place called Ronquières and pulled out bulletproof vests, ammunition, and a service firearm that had been stolen from a gendarme. The same stretch of canal had been searched in 1985 and the divers had found nothing. Forensic analysis done in 2013 concluded the items had only been in the water for a few weeks before they were "discovered" in 1986. Somebody who knew where the canal was going to be searched, and who had access to evidence from the case, wanted those items to be found at that time and not before.
In January 2019, a retired officer from the Delta unit was arrested on suspicion of evidence tampering. The Delta unit was the police group assigned to investigate the Brabant Killers. But he denied everything.
The closest Belgium has ever come to a name is Christiaan Bonkoffsky who was part of the same special forces unit whose ammunition type matched the gangs shotguns. Dismissed from the unit in 1981 for an accidental discharge, the year before the first attack. Originally from Aalst, which was the town of the final attack. When he died in 2015, his brother kept quiet for two years and then went on Belgian television in 2017 and said Bonkoffsky had confessed on his deathbed. He said he was the Giant.
Bonkoffskys height fit the sketch, his military background fit the tactics. His hometown fit the location of the final attack. His dismissal in 1981 also fit the timeline. In 2018, Belgian police announced that DNA from Bonkoffsky did not match samples from the crime scenes. The investigators who disputed the result pointed out something the state never publicly addressed. The DNA at the scenes belonged to three men. Ruling Bonkoffsky out of being one of them does not rule him out of being the other two. Noone officaly questioned this after.
The Belgian Gendarmerie itself had been founded in 1795. It survived Napoleon, two world wars, and the entire Cold War. The Brabant Killers case was one of the contributing reasons it was abolished in 2001. Three men with shotguns and face paint did what no foreign army had managed in two hundred years. They killed an entire branch of Belgian law enforcement.
On the 28th of June 2024, the federal prosecutor of Belgium stood at a press conference and closed the case. The numbers she gave were 1,815 leads checked, 2,748 sets of fingerprints examined, 593 DNA samples compared, and zero identifications. When she finished speaking, a woman named Irena Palsterman, whose father Jan was killed in the Aalst Delhaize parking lot when he was 40, said three words in Dutch. "Vandaag begraven we Vrouwe Justitia" which translates to: "Today we bury Lady Justice."
The federal prosecutors office was still publicly asking, as recently as 2020, for help identifying a man with a three and a half centimetre wine stain birthmark on the back of his neck. He took part in the Beersel raid in October 1983 and multiple witnesses described the birthmark in detail. That birthmark has been on the back of someones neck in Belgium for forty years. Either he died, or he is alive and old now, and nobody who ever spent time around him made the phone call.
In 1986 somebody mailed Belgian police an anonymous photograph of a man holding a Franchi SPAS 12 combat shotgun, standing in a forest. The note that came with it said the man was a very important person in the Brabant Killers case. The photograph was reissued by federal prosecutors in 2020 and ran on the front pages of Belgian newspapers. But nobody came forward.
Whoever those three men were, they had access to classified factory contracts, special forces ammunition, gendarmerie tactics, advance knowledge of police canal searches, and somebody on the inside who pulled an armed patrol away from the Aalst Delhaize fifteen seconds before they opened fire on it. Belgium did not fail to find them because the case was unsolvable. Belgium failed to find them because somewhere along the way, finding them stopped being the point. 28 dead, 22 wounded, 40 years of state silence, one prosecutor at a podium in 2024 saying it is over.
David Van de Steen is 50 years old now. Rebecca would have been 51 this year.
Under a law passed by Belgium in 2024, the case has no statute of limitations and can be tried at any time, by anyone. If anyone is left to try.
