Introducing: Hunting the Suicide Salesman

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.More episodes of Hunting the Suicide Salesman are available wherever you get your podcasts, and here: https://link.mgln.ai/HTSSxSKS

Someone Knows Something Introduces | Allison after NXIVM from Uncover

You think you know the NXIVM story. The secretive self-help empire. The sex cult headlines. The downfall of its leader, Keith Raniere. But the most famous woman at the centre of the story has remained largely silent. Allison after NXIVM from Uncover tells the story of Allison Mack: former Smallville actress, high-ranking NXIVM member, and convicted felon. With exclusive access following her release from prison, this series traces her astonishing path from Smallville fame to NXIVM’s inner circle — and her effort to rebuild a life in the wreckage. Through raw interviews and revealing conversations with those who knew her before, during, and after NXIVM, this season dives deep into the gray zones of influence, accountability, and redemption.

Introducing: Hell and Gone Murder Line from iHeart Podcasts | Doug Janis Part 1

From iHeart Podcasts and School of Humans comes Hell and Gone Murder Line. On December 13, 2020, in Hemphill, Texas, police in Sabine County got a call about a houseboat on fire. The houseboat was docked behind 322 Echo Ridge, off of Cedar Grove Road on Highway 21 in the Pendleton area of Toledo Bend. And the scene very quickly descended into total chaos. The firefighters had trouble getting out to the remote location, and by the time they got there the boat was engulfed in flames. Firefighters and paramedics rushed to the boat but it was too late. By the time they got there the walls had caved in. And then, when they dug through the remains of the boat, they found the body of 64-year-old Doug Janis. At first, they thought that the fire had been some kind of accident and that Doug had died as a result of a propane leak. But then, they took Doug's body in for an autopsy, and they found two bullets in his head. Doug Janis had been murdered. And his much younger wife April Mae Janis was nowhere to be found. But Doug’s death was just the beginning of a story that goes back twenty years and involves sex, allegations of corruption, and multiple murders.More episodes of Hell and Gone Murder Line are available at: https://podcasts.apple.com/us/podcast/hell-and-gone/id1437808691
