In Episode 4, I interview the first on the scene at the Camp Drinkwater Massacre, an EMT named Charles, who was only 19 at the time. Now forty years later, he reflects on that terrible day. I also have a clip of Charles talking to a police officer that evening. You can hear the sirens, the chaos, and the shock in his voice. You can also hear Carrie, the only survivor humming in the background. If anyone knows what she is humming, send us an email at [email protected].
