Joshua was stabbed twice in the chest over a £20 drug debt as he made his way home from college. CCTV footage played in court also showed the final moments before the stabbing. It captured the killer walking into the station with his girlfriend before leaving her behind to pursue Joshua and a friend. On platform two, the footage showed Joshua being stabbed and lifting his jacket and shirt to expose the wounds just moments before he collapsed.
