A teenager has pleaded guilty to murdering 12-year-old Birmingham schoolboy Leo Ross by stabbing him in the stomach during a random attack in parkland. Leo died after being taken to hospital from a riverside path in Shire Country Park, Hall Green, Birmingham, on 21 January last year. He denied assault occasioning actual bodily harm and assault by beating in relation to two other people and those charges were ordered to lie on file. It also emerged that Leo had no connection with his attacker and was killed in what senior officers believe was a random and unprovoked stabbing. The defendant’s guilty pleas were entered more than six months after a trial was postponed to allow psychiatric assessments.
