A local newspaper named De Stentor did some research into this matter and contacted a former police officer from the area. According to the police officer, the accident indeed took place near Raalte on the N348 between Raalte and Deventer, but not on the location where the 66.6 kilometre marker currently is, but near the 60.0 kilometre marker. Richardson may have misread the marker. At a glance a zero might look like a six.
