The police in the Netherlands are trying a new method to solve forgotten crimes. Dutch authorities have circulated calendars in five of the largest prisons in the Netherlands in which 52 cold cases are described. The Cold Case team hope that the new calendars provides tips on unsolved crimes. There are about 1,500 cold cases in the Netherlands. The Netherlands is the first country to try out this specific method. If this system succeeds the calendar will be introduced in several other prisons across Europe.
Research has shown that around 800 people in the Netherlands are walking around with information about these cold cases. These researchers also found out that a perpetrator often starts talking about his crime after time has passed. They feel safe, they got away with what they did and since it has been so long they forget that they can still go to prison for what they did.
Murders and disappearances
The 52 cases described in the calendar can be found here. Most of the cases described in the calendar are about murders such as the murder on Glenn Crawfurd in Almere (1995). The one on Peter Koster in The Hague (2008) and Koos Drevijn in Delft (2007).
But the calendar also includes a few missing and a grave robbery in which the victim was raped. There is a PDF version of the calendar which can be seen here.
No major criminals
What stands out in the selection of crimes is that no cases about the murders on major criminals are included in the calendar. The murders of John Femer , Sam Klepper, John Mieremet or Jaap van der Heiden are not on the calendar.
There’s are reward being offered for each case that is included in the calendar 800,000 euros have been made available just for the information that leads to the person whom committed the crime. Authorities know that these people won’t talk for free and therefore decided to use a small stimulant.
The cold case calendar is part of a broader offensive by the police to move potential witnesses of unsolved crimes to share their knowledge with the police. Thats why the television program Investigation Requested will pay regular attention to cold cases this year. Crime Site brought out the book Cold Cases in 2012. The police decided not to cooperate in most of the cases that are now placed in this calendar.
Last year some cold cases were solved, such as the gay murders in the Kralingse forest in 1993. This was done through DNA research.
