HARTFORD, Conn. (AP) – Forensic expert Henry Lee on Sunday gave himself only a 50 percent chance of figuring out what happened to a Greenwich man who vanished from his honeymoon cruise in the Mediterranean Sea last summer.

“I would say 50-50,” Lee said on “Face the State” on WFSB-TV. “It all depends on how much evidence they have so far collected and preserved.”

Lee said he will go on board the ship Jan. 23 to conduct his examination into the case involving George Allen Smith IV of Greenwich who disappeared July 5. Royal Caribbean officials have limited his time aboard to two hours, he said.

Lee, who has testified in numerous high-profile cases, including the trials of O.J. Simpson, William Kennedy Smith and Kennedy cousin Michael Skakel, was hired by Smith’s bride, Jennifer Hagel-Smith. He said he initially was reluctant to take up the case.

With between 600 and 700 cases, he said his immediate response was, “I’m too busy to handle that.”

But because Smith has been missing for six months, “the family needs some answers, which I feel pretty moved by their request,” Lee said.

He has already eliminated one possible cause of death.

Because Smith’s body was not found, “we can safely eliminate a natural cause,” Lee said.

Blood stains were found on a canopy that covers life boats. No one has been charged and no body has been recovered.

The canopy will figure prominently in his investigation, he said. “We have to look at the canopy to see if there’s any indentation or not,” he said.

Smith weighed more than 200 pounds and the distance from his cabin to the canopy was 22 feet or more, Lee said.

“With that kind of body weight and distance, if somebody dropped from the top, we should see any indentation, any blood splatter,” he said.
