August, 2005: Chuck Rutherford and Lana Stempien, two popular Detroit attorneys, embark on an overnight cruise to idyllic Mackinac Island, off Michigan’s Northern Peninsula. She is a former model, turned lawyer; he is a fun-loving guy with a penchant for wearing loud ties in court. They seem to be deeply in love.

With a lifetime of boating experience behind them, they set out on a sunny, summer day in her 27-foot cruiser, called Sea's Life. Then, after a brief stop for lunch on their second day out on lake Huron, the couple simply disappears.

Their boat is recovered the next morning, drifting aimlessly in worsening seas. The motor is still running, the radio is on, their personal belongings, untouched. Two weeks later, Lana's nude body washes up in a rocky bay. Chuck has never been found.

The Michigan State Police are calling the incident a tragic accident but Lana's family isn't buying it. Could Sea's Life have been a floating crime scene?

This weekend, join host Greta Van Susteren as FOX News investigates shocking new clues that could reveal what really happened that day on Lake Huron's "Dark Waters."
