One of the biggest mysteries that many of us have grown up with is the death of Natalie Wood. Can you believe that It's been almost 40 years since she drowned? She was only 43-years-old. Over the years we have heard so many stories about what may have really happened that night. What we do know is that Natalie Wood was on-board the  yacht "Splendour" with husband, Robert Wagner, actor Christopher Walken, and the captain of the boat, Dennis Davern.

After all of these years, reports that 87-year-old Robert Wagner has just been named a "person of interest" in the death of his wife. 

The Thanksgiving weekend tragedy was ruled an accident in 1981 after Wood's body was found in the water near Catalina Island in California. However, the case was reopened in 2011 because Captain Davern told authorities that he heard Wood and Wagner arguing that night. In 2012, Natalie Wood's death certificate was amended with "drowning and other undetermined factors."

A special 48 Hours will air this Saturday at 10:00pm on CBS "Natalie Wood: Death in Dark Water" which will feature interviews from investigators in the case.
