When a British father, Matt Jeffrey, was killed by a single punch during a stag do on the Greek island of Zante, two men were convicted. 

But now a Sky News investigation has identified a new suspect - a man who has potentially evaded justice for years.  

In this episode, Niall speaks to Jason about the devastating impact of ‘one-punch’ violence, the emotional toll on Matt’s family and the complexities of an international legal battle.
