In the early hours of 23 October 2019, a grim discovery was made on an industrial park in Grays.The bodies of 39 people were found dead in a refrigerated lorry. 29 men, eight women and two 15 year-old boys had suffocated. We later learned the victims were all Vietnamese migrants. On this episode of the Sky News Daily podcast with Dermot Murnaghan, we hear their stories as a people smuggling gang await sentencing in January for manslaughter. Why did they seek to leave Vietnam in the first place? What went wrong? And what’s being done to stop others facing a similar fate?Dermot is joined by Sky’s South East Asia correspondent Siobhan Robbins, our crime correspondent Martin Brunt and Dr Tamsin Barber - a senior lecturer in sociology at Oxford Brookes – as we examine the story beyond the headline.Daily podcast team:Podcast producer - Annie JoycePodcast producer - Nicola EyersPodcast producer – Emma-Rae Woodhouse Interviews producer - Oli FosterInterviews producer – Ella GriffithArchive - Simon WindsorMusic - Steven Wheeler
