About Monster: Hunting the Long Island Serial Killer
A decade ago, filmmaker Josh Zeman was on the hunt for the country’s most elusive serial killer. One who left nearly a dozen bodies along the beaches of Long Island. While he got close to catching him, it wasn’t until 2023 that authorities finally made an arrest. The troubling part is... the answers were there all along, hidden in plain sight. So why did it take authorities so long to catch him, and how many lives could have been saved? From Tenderfoot TV and iHeartPodcasts, a new installment in the Monster franchise is coming November 17th. This is 'Monster: Hunting The Long Island Serial Killer'. An investigative podcast into the most notorious killer in New York– since the Son of Sam.

NEW: High Strange S2 - From Tenderfoot TV
High Strange Season 2 goes deeper into real encounters, credible witnesses, and the explanations that never seem to stick. More firsthand accounts. Bigger moments. And more times where the official story starts to wobble. This isn’t about believing everything. It’s about following the story until it actually makes sense… or until it gets too strange to ignore. New season. Same curiosity. Same skepticism. Still probably not a weather balloon.

[…] Words written and in some cases spoken by the people who knew these women best. The people who carried their absence every single day. And now this is the one moment in the entire process where they're given the floor to speak directly to the court, and more importantly, to Rex Jorman. Your Honor, Ms. Danielle Mack, adopted sister of Valerie Mack, wishes to address the court. Today, I'm here to talk about the impact of Mr. Jorman's crimes.
