In this chilling episode of Serial Killer Files by Skoob, we uncover the disturbing case of Marybeth Tinning, a woman whose nine children died under mysterious circumstances between 1971 and 1985. Each death was explained away as illness, SIDS, or accident—until one autopsy exposed a horrifying pattern of infanticide.

We examine the warning signs that were missed, the psychology behind Munchausen syndrome by proxy, and why justice came far too late.

In the early 1900s, long before criminal profiling or modern forensics, one killer changed true crime forever. John Frank Hickey — known as The Postcard Killer — didn’t just murder. He wrote letters.

In this chilling episode of Serial Killer Files by Skoob, we uncover the terrifying story of a man who taunted police, tormented grieving families, and mailed detailed confessions of his crimes.

You’ll hear how investigators tracked him through handwriting analysis, how his own letters sealed his fate, and why this case is considered one of America’s earliest serial killer investigations. Even more disturbing are the unanswered questions — how many victims were there really, and how close did he come to getting away with everything?
