Zero Signal Shorts: The CIA’s Heart Attack Gun

In 1975, during a Senate hearing known as the Church Committee, CIA Director William Colby revealed something that looked like it belonged in a James Bond film — a dart gun designed to fire frozen poison and mimic a fatal heart attack. The weapon was part of MKNAOMI, a little-known Cold War program where the CIA, working with the U.S. Army, stockpiled lethal toxins and built covert weapons hidden from public view. In this short-form episode of Zero Signal, we dive into the truth and the conspiracy: what MKNAOMI was, the toxins it stored, the infamous “heart attack gun,” and the lingering question — if the CIA kept poisons on ice after they were ordered destroyed, what else might be hidden today? 👉 For more deep-dive episodes on conspiracies, secrets, and history’s shadows, tune in every Tuesday at 6 a.m. Credit:Portions of this episode include content provided courtesy of C-SPAN.Source: C-SPAN – CIA Director William Colby, The Church Committee, and the Shellfish Toxin Dart Gun Exclusive Listener Discounts: Support the show and grab exclusive deals from our sponsors Using Code ZEROSIGNAL Aspire Drinks – Green tea-powered healthy energy. 👉 20% OFF at ASPIREDRINKS.COM Prep Starts Now – Conquer uncertainty, one step at a time. 👉 15% OFF at PREPSTARTSNOW.COM Zivolife – Exclusive patented superfood! 👉 30% OFF at ZIVO.LIFE Klear Protein – Elevate your protein game with Klear Whey Protein Powder.👉 20% OFF at KLEARPROTEIN.com HyperNatural – The Best Men’s Polo Shirts-Men’s Journal 👉 20% OFF at HYPERNATURALSTYLE.COM 📱 Connect with Zero Signal: Reddit, BlueSky, X, TikTok, and YouTube
