Hysterical investigates a mysterious illness that spreads among a group of high school girls in upstate New York. What is causing their sudden, often violent symptoms? Is there something in the water or inside the school? Or is it “all in their head?” The series examines the outbreak in LeRoy, NY, believed by some to be the most severe case of mass hysteria since the Salem Witch Trials. In his search for answers, Dan Taberski (9/12, Missing Richard Simmons, Running from Cops) explores other seemingly inexplicable events of the last few years – CIA officers being crippled with nausea and vertigo; cops OD'ing from exposure to fentanyl – and discovers they’re far more connected than we realize.

From Wondery and Pineapple Street Studios, this 7-part series forces us to grapple with the mysteries of our own minds, and reckon with a contagion that we thought was long dead, but may be the defining disorder of our time.

The trial of Raynella Leath is unlike anything Erin Moriarty has covered before. It all began in 2003 with a frantic call to 911 when Raynella said she found her second husband David Leath dead of a single gunshot wound and called 911 to report it as a suicide. However, his autopsy said otherwise, and 14 years later, Raynella stood in court on trial for his murder. Hear the beginning of Raynella Leath’s story and how the widow’s web begins to unravel. This is the first episode of Married to Death from My Life of Crime with Erin Moriarty, available on Amazon Music or wherever you get your podcasts. New episodes on Wednesdays.
