Investigators Seize Explosive Video Of Robert Wagner's Natalie Wood Death Confession

Police investigating Natalie Wood's death are reviewing RadarOnline.com's exclusive video of the explosive confrontation between Robert Wagner and the screen siren's sister Lana Wood!

"I'm interested in seeing the video to hear what he says, and seeing his reaction," homicide investigator Lt. John Corina of the Los Angeles County Sheriff's Department told RadarOnline.com.

According to Corina, Wagner's recent talk with Lana that was caught on tape will be the first time in years that investigators have had a chance to see what the Hart to Hart actor has to say about his wife's death, since the 85-year-old star has refused to cooperate with the re-opened criminal investigation.

As RadarOnline.com reported, Lana confronted Wagner on Feb. 12 in Palm Springs, Calif. Lana, 70, begs her brother-in-law to finally come clean about what really happened to her sister in 1981 when she fought with Wagner aboard a yacht and was later found drowned to death.

"Lana, why would you even bring up anything like that?" Wagner snapped at her during the tense showdown.

"I have talked to everybody," he snapped. "You have accused me! ... You have accused me of murdering her!"

Wagner's lawyer insists his client has "fully cooperated" with cops and vehemently denies any wrongdoing.
