Written by: Darren Dedo Case Filed: 06/29/01 - Vicksburg, Mississippi Executive Producer: Rick Garner The Mississippi River holds many mysteries, like disappearing ships and ghostly figures that wander steamboat decks. "From time to time we have crew members report...they heard something strange in the night, or they saw a figure out on the deck early in the evening, that just sort of vanished..." Steamboats like the Delta Queen proudly cruise the Mississippi River. Captain Mike Williams has seen and heard some unexplained things while piloting the ship. "Thought I heard strange voices and doors slamming...when no one else was onboard and things like that."
