Sophia Koetsier

She was Sophia Koetsier, a 21-year-old Dutch medical student.

On 28 October 2015 she vanished in Murchison Falls National Park, Uganda, after walking toward the toilets near the student centre at Paraa.

Her underwear was later found hanging five metres up in a tree. Her bag, a clean shoe, sunglasses and torn strips of her trousers were arranged along the riverbank in a way that looked staged.

She has never been found.
