Elianne Andam, a 15-year-old girl, was fatally stabbed in Croydon while defending her friend during a confrontation over a teddy bear. The accused, Hassan Sentamu, 18, admits to manslaughter but denies murder, citing diminished responsibility due to autism. The attack, captured on CCTV, left Elianne severely injured, with the knife penetrating deeply into her neck. The trial seeks to determine the influence of Sentamu’s autism on his actions. A mural in honor of Elianne has been unveiled in Croydon.
