Gouda brother murder: 26‑year‑old sentenced to six years and compulsory psychiatric care

A 26‑year‑old man from Gouda, identified as Arie M., was convicted by the Hague court for fatally stabbing his older brother in their family home on 26 August 2025. The victim suffered 135 stab and slash wounds and died at age 29. Arie M. fled the scene, was apprehended nearby with severe injuries, and later claimed he experienced a “blackout” and a religious‑tinged delusion during the attack. The court described the violence as belonging to a “category beyond ordinary cruelty.” He received a six‑year prison term together with a TBS (detention under hospital order) sentence and mandatory forced treatment for his diagnosed psychotic disorder.

The sentencing follows earlier reports of family tension and the suspect’s refusal to seek mental‑health help. Prosecutors highlighted the extreme nature of the crime and the need for psychiatric supervision alongside incarceration.
