On January 13 a bag containing the dismembered limbs of teenager Keane Mulready-Woods was found on a housing estate in Dublin. Keane is believed to have worked for a drugs gang in the coastal town of Drogheda, just north of Dublin, and his murder is thought to be gang-related. Two rival gangs are feuding in Drogheda over turf and the booming cocaine market. These gangs use social media to taunt each other, often with devastating results.

In this episode we speak to Nicola Tallant, investigations editor of the Sunday World, who’s been following the story of Ireland’s gangs. We also talk to Joanne O’Dwyer who works in rehabilitation in Drogheda. She tells us about how the murder has affected the town.
