In a landmark retrial in Serbia, the parents of a teenage school shooter have been handed prison sentences for their role in the tragedy, a verdict that has sparked an urgent call from British psychologists for a broader investigation into systemic failures. The case, which has gripped the nation, raises profound questions about digital surveillance, mental health support, and the ethical boundaries of parental responsibility in the age of algorithmic isolation.
The shooter, a 15-year-old boy, killed nine classmates and a security guard at his Belgrade school in 2023 before taking his own life. Initially, his parents received suspended sentences for illegal weapons possession. But a public outcry and new evidence of their negligence prompted a retrial. This week, a judge sentenced the father to four years and the mother to three years for “failing to prevent a crime” and “child neglect.” The court found that they ignored multiple warning signs, including his obsession with violent video games and dark web forums, and failed to secure his legally owned shotgun.
The verdict has been met with mixed reactions. Many Serbs feel justice has been served, but British experts argue that focusing on the parents alone misses a deeper, more troubling pattern. Dr. Helena Cross, a child psychologist at King’s College London, told our reporter: “This case is a symptom of a broken ecosystem. We cannot place the entire blame on two individuals when the boy was isolated by algorithms, radicalised by anonymous communities, and weaponised by a culture that celebrates digital violence without meaningful interventions.”
Dr. Cross is among a growing group of British psychologists calling for a wider inquiry into the role of tech platforms and school mental health services. They argue that the shooter was a product of a “digital echo chamber” where his depressive thoughts were amplified by recommendation algorithms. His social media feeds, later analysed by experts, showed a steady descent from gaming forums to incel communities and finally to instructional videos on building improvised weapons.
“The parents were neither tech-savvy nor equipped to monitor his online life,” said Dr. Cross. “They didn’t see the signs because the signs were hidden behind encrypted chats and private browsers. This is a failure of digital literacy, of school safeguarding protocols, and of platform design. A wider inquiry would examine how these systems can be redesigned to prioritise safety over engagement.”
Silicon Valley, where I spent a decade observing the product cycles of social media giants, has long resisted such regulation. But the Serbian case adds weight to calls for a “digital duty of care” similar to the UK’s Online Safety Act. The Act, passed in 2023, mandates that platforms protect children from harmful content, but its enforcement has been slow. Dr. Cross argues that the Act must be extended to include proactive detection of radicalisation patterns, not just reactive content moderation.
The parents’ sentencing also brings up uncomfortable questions about the limits of parental liability. In a world where children’s digital lives are opaque, can we expect every parent to become a cybersecurity expert? Or should we demand that platforms provide better tools for parental oversight, as well as transparent data on their algorithms’ effects?
The Serbian court’s decision, while legally sound in its national context, feels like a band-aid on a systemic wound. The boy was failed by his parents, yes, but also by his school, his peers, and the digital ecosystem that guided him towards darkness. British psychologists now call for a UK-led inquiry that could set a precedent for how we treat such tragedies in the future.
Quantum leaps in computing and AI have given us tools to predict behaviour with startling accuracy. But if we only apply these tools to punish after the fact, we are missing the point. The real work is in prevention: designing systems that recognise despair before it becomes violence, and giving parents the digital literacy to see through the screen into their child’s soul.
As this story unfolds, one thing is clear: the parents of the Belgrade shooter are in prison, but the algorithm that guided his hand remains free. The question is not whether we can hold individuals accountable, but whether we have the courage to question the architecture of our digital lives.
