Dennis Davern, The captain of Robert Wagner's yacht, the Splendour, has admitted in a sworn declaration to the Los Angeles County Sheriff's Department that he gave Natalie Wood, Christopher Walken, and the Hart to Hart star Quaaludes, a powerful sedative, RadarOnline.com is exclusively reporting.

The Los Angeles County Sheriff's Department announced last Friday that the Natalie Wood case was being reopened because of new evidence that they had received. A spokesman also firmly stated that Robert Wagner is not a suspect in his wife's death.

In 2008, Dennis Davern and Margaret Rulli wrote a book about the tragic weekend that Natalie died entitled Goodbye Natalie, Goodbye Splendour; in it, he writes about alcohol and drug use on board the yacht on that fateful night in 1981.

He's now taken his recollections about drugs and booze a step further, and sworn to it in his declaration.

Almost 30 years after she drowned while yachting off the coast of California's Catalina Island, the world is again fascinated with Natalie Wood as the police reopen the investigation into her death.

Many who are following the developments weren't even born when the beautiful actress mysteriously fell to her death, and RadarOnline.com is taking a look back on the life and death of the movie star.

Born in 1938, Wood was a successful child actress during the golden age of Hollywood and her part in the Christmas classic Miracle On 34th Street remains a holiday-viewing staple to this day.

Police investigating the drowning death of Natalie Wood revealed in a news conference on Friday that her then-husband Robert Wagner is not a suspect, RadarOnline.com has learned.

Lieutenant John Corina said that new information is "substantial enough" to justify taking another look at the case but did not comment about any possible arrests or confirm if ship captain Dennis Davern had been questioned.

As RadarOnline.com previously reported, the famous 1981 case was officially reopened this week after homicide investigators received new information in the longtime Hollywood mystery.
