John S. has been sentenced to 30 years in prison and mandatory treatment for killing a shoemaker and two individuals at a care farm in Alblasserdam. The court ruled that a shorter sentence did not reflect the severity of his crimes. Mental health experts indicated that S. is significantly impaired in his ability to understand his actions, increasing the risk of reoffending. The prosecution argued that his actions have shocked society, warranting a lengthy sentence followed by rehabilitation efforts.
