Demon Legion Hell sound caught on tape? During a live ghost hunt broadcast last year at the Sallie House we captured a Hellish Sound while performing a Ghost Box session, the same sound was later captured during an investigation in California a year later from which it claimed to be from legio, or legion. Could this be a demon trying to communicate? Or possibly a real sound from hell? All video and audio from these clips were gathered from our live investigations which are broadcasted on Youtube.
