Utrechtse Heuvelrug – She was found dead, without clothing, laid out in a shallow hole and covered with leaves near the De Heul parking lot. She couldn’t have been older than 15 years old. And it was clear that she had been dead for a long time. In the absence of an identity, she was named after her location: the Heul girl. But after fifty years and years of investigation by the police and the Public Prosecution Service, her name is still unknown.
