The Murder of Marianne Vaatstra

In May 1999, 16-year-old Marianne Vaatstra was raped and murdered in a field near her home village in the rural Friesland province of the Netherlands. The case drew national attention and, for years, fueled unfounded public suspicion toward residents of a nearby asylum seekers' center.

A 13-year cold case

Despite an extensive investigation, the case remained unsolved for over a decade. In 2012, Dutch police undertook a large-scale, voluntary DNA testing effort among thousands of local men in the area to try to match crime-scene evidence.

Resolution

The DNA campaign identified a local dairy farmer, Jasper S., as a match. He confessed and was convicted in 2013, sentenced to 12 years in prison — a sentence that reflects the generally shorter terms typical under Dutch sentencing guidelines compared with some other countries.

Legacy

The case led to public apologies to the asylum seekers' community that had faced years of unfounded suspicion, and remains a landmark example of mass DNA screening solving a cold case.
