In 1982, a wave of terror swept across the Chicago area and the rest of the United States as seven people suddenly died; the manner of death was homicide; the cause: POISON! Tampering, someone had spiked Tylenol capsules with cyanide and American changed overnight. This shocking crime left the public in fear; anyone could have been targeted! For 44 years, an extensive investigation aimed to uncover the truth, but the case grew cold, leading many to believe that the cunning killer had escaped justice. Now, however, there is a startling revelation. Forensic psychologist Joseph Cibelli has unveiled his father's deathbed confession, presenting compelling evidence that has led him to a shocking conclusion: his father is the infamous Tylenol Killer.

Part I: A boy meets a girl, and love ignites. They marry, craft a life together, and welcome their son and daughter, a perfect family. But as time unfolds, pressures rise, people evolve, and dreams unravel. While divorces are part of many people's stories, Jeff and Jill Cahill's tale is far from ordinary. It's a nightmare that shocks and devastates at every turn. When their lives take a dark twist, disastrous choices have ripple effects that devastate those around them. Families are shattered, hearts are left in ruins, and overwhelming confusion leaves us questioning: "How can anyone treat another human being this way?" Part I of While She Slept by Marion Collins challenges us to reflect on the fragility of love and the consequences of domestic violence.

It's time to start a conversation! The amazing David Lyons, a retired homicide detective and co-host of The Murder Police podcast, is Jill's guest. These podcast hosts have an important discussion about David's new book, True Crime and Consequence. In it, David Lyons examines the increasing influence of the true crime community on real-life investigations. This timely work raises important questions about how podcasts, social media, and amateur sleuthing impact investigations, for better or worse. How can everyday citizens ethically, legally, and compassionately contribute to solving cases? AND- David and Jill delve into specific cases affected by social media, including the recent verdict involving Ashley Guillard, who was ordered to pay $10 million in damages to an innocent college professor she falsely accused of being involved in a mass murder.
