Still missing after 10 years: Sophia Koetsier
On October 28, 2015, 21-year-old Dutch national Sophia Koetsier disappeared in Murchison Falls National Park, Uganda. Despite several searches by both Ugandan and Dutch authorities, no trace of her has ever been found.
The Dutch non-profit Peter R. de Vries Foundation is offering a €10,000 reward for information that brings clarity about Sophia’s fate. The reward will be paid upon confirmation through a DNA match.

If the definitive tip comes through, we, Sophia’s family will increase that amount.
It goes without saying that the reward is only paid after Sophia is found, not before.
