Homicide detectives probing Natalie Wood's mysterious death questioned Tuesday the woman who allegedly overheard the screen siren crying for help, RadarOnline.com has exclusively learned.

Cops from the Los Angeles County Sherrif's Department interrogated retired stockbroker Marilyn Wayne at her Los Angeles home.

Wayne is considered a sensational new "ear witness" in the case. She was a guest on an adjacent yacht, roughly 90 feet from the Splendour, the yacht on which Wood, 43, was cruising with her husband Robert Wagner and actor Christopher Walken in 1981, just hours before her Thanksgiving weekend death.

The woman who allegedly overheard screen siren Natalie Wood crying for help has claimed she also heard a slurring Robert Wagner tell a woman overboard "we're coming to get you."

Retired stockbroker Marilyn Wayne is considered a sensational new "ear witness" in the mysterious case. She was guest on an adjacent yacht, roughly 90 feet from the Splendour, the yacht on which Wood, 43, was cruising with her husband Wagner and actor Christopher Walken in 1981, just hours before her Thanksgiving weekend death.

While Wayne has yet to be questioned by Los Angeles police who announced last week they were reopening the three decade old cold case, RadarOnline.com has exclusively learned they've been provided with a sworn declaration from her that reveals telling clues.

It forms part of what law enforcement has said is "substantial new evidence" that triggered their decision, but is not an indication of any wrongdoing on Wagner's fault.
