Summary

A Malaysian teenage boy accused of murdering a schoolmate by fatally stabbing her at their secondary school near Kuala Lumpur was found not guilty due to insanity. The court heard that the 14-year-old boy, who suffers from schizophrenia and had been experiencing delusions since age nine, acted under severe mental distress exacerbated during the pandemic. As a result of the verdict, the boy will be admitted to a psychiatric hospital for treatment until he is considered ready to return to society, likely with annual assessments. The case has prompted discussions about limiting children's access to social media and led to new regulations banning minors under 16 from using major social media platforms.

Story summary

A 14-year-old Malaysian boy has been acquitted of murder after fatally stabbing his 16-year-old female schoolmate Yap Shing Xuen in a toilet at their secondary school on the outskirts of Kuala Lumpur. The case shocked Malaysia and raised concerns about social media's impact on children, leading authorities to restrict access to social media for young users earlier this year. During the trial, defense lawyers argued that the boy suffered from schizophrenia and severe mental health issues since he was nine years old, based on testimony from a psychiatrist who evaluated him. The judge acquitted the boy on grounds of insanity, finding that his poor mental state during the incident negated criminal responsibility despite acknowledging the act itself.
