The Death of Nicky Verstappen

An eleven-year-old at summer camp

Nicky Verstappen was 11 years old in the summer of 1998, a boy from the Dutch province of Limburg who had gone away with other children to a youth summer camp on the Brunssummerheide, a stretch of heath and woodland in the south of the province. Camps like this were an ordinary part of a Limburg childhood, and nothing about the week suggested danger. That changed during the night of 9 to 10 August, when Nicky vanished from the tent where he had been sleeping.

A disappearance on the heath

His absence set off a search across the heath. The next day his body was found in the area surrounding the camp. Investigators concluded that he had been taken from the campsite and had died a violent death. Traces of an unknown man's DNA were secured from his body and clothing and carefully stored. For years those traces were the strongest lead in a case that otherwise stalled, and the death of a child at a supervised camp became one of the most painful unsolved crimes in the Netherlands.

Twenty years without answers

For two decades the case went unsolved, and no direct match to the stored traces ever emerged. In early 2018 the police and the Public Prosecution Service (Openbaar Ministerie, OM) launched what they called the largest DNA kinship investigation ever undertaken in the country. Starting on 24 February 2018, about 21,500 men in the region were invited to give a cheek swab. Taking part was voluntary. The aim was not to find the killer directly but to find a male relative whose DNA was close enough to point investigators toward a family.

On 22 August 2018 the OM announced a breakthrough. The comparison had led investigators to a 55-year-old man from the region, named by authorities as Jos B. and widely reported as Jos Brech, whose DNA matched the stored traces. His whereabouts were unknown; his family had reported him missing earlier that year. A few days later, acting on a tip from a witness, Spanish police tracked him down. He was found in a remote wooded area outside Barcelona, where he had been living rough, and he was arrested and extradited to the Netherlands.

Two trials and a final ruling

The trial before the District Court of Limburg ran from late September to mid-October 2020. Prosecutors asked for 15 years in prison plus a hospital order (TBS). Brech has always denied the charges. On 20 November 2020 the court convicted him of sexually abusing the boy and of depriving him of his liberty, but found manslaughter not proven, and sentenced him to 12.5 years. Both the prosecution and the defence appealed.

At the appeal, prosecutors sought 20 years, pointing to 27 DNA traces on Nicky's body and clothing that matched Brech's profile. On 28 January 2022 the Court of Appeal in 's-Hertogenbosch went further than the lower court: it found the abuse, the deprivation of liberty and manslaughter proven, also convicted him of possessing child sexual abuse images, and imposed 16 years. The judges noted that the parents had waited more than two decades for answers and that Brech had never shown remorse for the boy's death.

Brech then took the case to the Supreme Court (Hoge Raad), which does not reassess the facts but checks whether the law was applied correctly. On 26 September 2023 it upheld the conviction. Because the proceedings had taken too long, it reduced the sentence by three months, to 15 years and 9 months. With that ruling the case was closed in the Dutch courts, and the OM now lists it as concluded.

What happened to the DNA

The mass screening raised questions about privacy from the start, and what would happen to the samples mattered to the men who gave them. According to Belgian broadcaster VRT, around 15,000 of the men invited eventually took part. Participants could choose whether their material was destroyed straight after comparison or only when the criminal case had ended; nearly 2,200 chose immediate destruction. In early February 2025, after the case was final, all remaining samples, profiles and digital files from the investigation were destroyed.

Why the case matters

The Verstappen case became the defining example of familial DNA searching in the Netherlands. That technique, which looks for relatives of an unknown offender rather than the offender himself, only became possible after Dutch lawmakers amended the Code of Criminal Procedure. Parliament passed the DNA kinship research bill in 2011 and it came into force in 2012, giving investigators an explicit legal basis to check whether a blood relative of someone whose DNA had been examined could be the person they were looking for.

The Limburg operation showed that this approach could work on a very large scale, two decades after a crime, and that a conviction built on it could stand up through three levels of the court system. It also showed the trade-offs: tens of thousands of uninvolved men were asked to hand over genetic material, and the way their samples were handled and finally destroyed became part of the case's legacy. For Nicky's family, the outcome came after more than twenty years of waiting.
