Amsterdam police are seeking a specific witness to the double homicide of two Syrian teenagers, Mohammed (18) and Mohammad (16), who were fatally shot in Piet Wiedijkpark on January 1, 2026. Authorities released Instagram footage of the potential witness, a man wearing white sneakers and a light jacket, entering the park from Theo Bouwmeesterhof. This unusual step highlights the police's urgent need for information. A 25-year-old man was arrested on January 20, 2026, as the suspected shooter. Investigators believe the victims were killed randomly, simply being in the wrong place at the wrong time.
