  1. Introducing: Hunting the Suicide Salesman

    Jun 3, 202648 min

    Following the critically acclaimed series Hunting Warhead, Season 2: Hunting the Suicide Salesman follows host Daemon Fairless as he takes us inside another dark corner of the internet: the online world helping people take their own lives. When people around the world started killing themselves with an obscure substance a few years ago, police were unaware that something – someone – was tying many of these deaths together. It took grieving families and investigative journalists to piece together what was actually happening and to trace the source of the substance – first, to an online suicide forum and then, to a salesman in Canada: Kenneth Law. Police believe he sent more than 1200 shipments to 41 countries… and may be connected to more than 145 deaths around the world.
