A 15-year-old boy has been found guilty of murder after a man was stabbed in the heart in a row over the youths messing around in a supermarket's toilets.
Ian Kirwan was found critically injured after being knifed in front of horrified shoppers at the Asda store in Redditch, Worcestershire, in March last year.
The 53-year-old, who worked as a software engineer for Jaguar Land Rover and left behind a dedicated wife, died at the scene despite the best efforts of medics and an off-duty nurse.
