Tanja, then 18, disappeared in August 1993 during an introduction week at Maastricht University. Years of investigation and various searches have never clarified the disappearance case. With a view to within a year tip money of one million euros last month – on Groen’s birthday – De Vries launched a fundraising campaign and tip line.
The stake of one million is high, but according to De Vries necessary to bring the truth to light. Smaller rewards don’t work, in his opinion. “An amount of 10,000 or 15,000 euros does not convince people so quickly to tell something that has been gnawing at them for years.” According to a police spokesperson, there are still ‘numerous scenarios’ about what could have happened to Tanja Groen.
