In a retrial that has gripped the Balkans and caught the attention of British legal minds, the parents of a 14-year-old who carried out Serbia’s worst school shooting in decades have been sentenced to prison. The verdict, delivered in Belgrade on Tuesday, saw both mother and father handed custodial terms for negligence that allowed their son access to firearms. The UK’s Ministry of Justice issued a rare statement praising the outcome as a ‘landmark for accountability in the digital age’.
The tragedy unfolded in May 2023 at the Vladislav Ribnikar primary school in central Belgrade. The shooter, identified only as K.K. due to his age, used his father’s legally owned handguns to kill nine classmates and a security guard before turning the weapon on himself. During the initial trial, the parents were acquitted on grounds of insufficient evidence linking their actions directly to the attack. But an appeals court ordered a retrial, citing new forensic analysis of the family’s digital footprint.
Justice Milica Jovanovic, presiding over the retrial, stated that the parents had ‘failed in their duty of care’ by leaving a gun safe unlocked and ignoring clear warning signs in their son’s online behaviour. Prosecutors presented evidence that the boy had been consuming violent incel ideology and had shared plans for the attack in encrypted chat rooms. The father, a 45-year-old doctor, received a 12-year sentence for illegal weapons possession and child endangerment. The mother, a 42-year-old accountant, was handed eight years for failing to report her husband’s reckless storage of firearms.
What makes this case particularly resonant for British observers is the parallel to the UK’s own Jonathan Law case, where a teenage shooter’s parents were prosecuted after their son used a legally held shotgun in a 2018 attack. A source at the Ministry of Justice told me: ‘This ruling reinforces that parental responsibility does not stop at the front door. In an age of algorithmic radicalisation, we must hold caregivers accountable for the digital environment they curate.’
The verdict has sparked a heated debate across the Atlantic about the limits of liability when children access weapons and extreme content. Serbia, a nation with one of Europe’s highest gun ownership rates, has seen strict new firearm laws introduced since the massacre. But tech ethicists are now asking: should parents also be charged for failing to monitor their children’s online radicalisation? The Electronic Frontier Foundation has warned against ‘policing the home server’, arguing that such laws could lead to draconian surveillance of family life. Yet the UK’s Online Safety Bill, currently moving through Parliament, includes provisions that would require tech platforms to flag extremist content to parents and authorities.
I spoke with Dr. Elena Markovic, a digital sociologist at the University of Belgrade, who told me: ‘This is a Black Mirror moment for Serbia. We are trying to legislate against horrors that emerge from the intersection of physical guns and digital propaganda. The parents are scapegoats for a system that failed to curb either.’ Her point is valid. Since the shooting, Serbia has banned TikTok and Telegram for users under 18, but enforcement has been lax. Meanwhile, the UK’s approach is to nudge platforms towards self-regulation, a strategy that critics say is too little, too late.
The case has also exposed a generational divide in how we conceptualise privacy. The parents’ lawyers argued that reading their son’s encrypted messages would have violated his rights. But the court ruled that a minor’s right to privacy does not supersede the right to life of his potential victims. This echoes the UK’s ‘duty of care’ framework, where tech companies are legally obligated to protect young users from harm, even if it means compromising encryption.
As the parents were led away to serve their sentences, the broader question remains: can any justice system truly deter the next school shooting when the tools of radicalisation are embedded into the apps children use daily? The UK’s praise for Serbia’s verdict may be premature. Without parallel efforts to tame the algorithmic firehose that feeds young minds with violent fantasies, we are simply locking the stable door after the digital horse has bolted. The real test will be whether other nations follow not just the sentencing, but the policy questions this case has thrown into sharp relief.
