A teenager from Ilkeston in Derbyshire has been convicted of the murder of 18-year-old Noah Smedley in the town.
Charles Hartle, 18, who was 17 at the time, stabbed Mr Smedley in the heart with a Rambo knife, which he had concealed in his trousers, after a group of friends had bought drugs from him on 28 December 2024.
Hartle stood at the back of the group and, once his friends had made the deal and were saying their goodbyes, he stepped forward, grinned and stabbed Mr Smedley.
