Conflicting versions of what happened on the yacht shared by Wood, her actor-husband Robert Wagner and their friend, actor Christopher Walken, have contributed to the mystery of how the actress died on Thanksgiving weekend in November 1981.

Two sheriff’s detectives are now diving into the mysterious events on the yacht Splendour, although whether they reach any different conclusions than their predecessors remains to be seen. They recently received new, seemingly credible information and heard from potential witnesses who weren’t included in the original investigation of Wood’s death, sheriff’s Lt. John Corina said Friday.

But he said nothing has happened to change the official view that Wood’s death was originally an accidental drowning. Wagner, the former star of “Hart to Hart,” is not considered a suspect, he added.

Corina released few details about who investigators have contacted or plan to re-interview, but the inquiry will certainly lead them to speak with the three survivors of the trip — Wagner, Walken and skipper Dennis Davern.

Wood’s sister, Lana, was not on the boat, but told CNN’s Piers Morgan on Friday that she has spoken with Davern many times and believes her sister did not fall off the boat.

“I don’t think she fell, I don’t know if she was pushed, I don’t know whether there was an altercation and it happened accidentally but she shouldn’t have died and that does stay with me and hurt,” Lana Wood said.

“I would prefer to always believe that RJ (Wagner) would never do anything to hurt Natalie and that he loved her dearly, which he did, and I don’t believe that whatever went on was deliberate. I’ve always cared about him. I always will care about him,” she said.

Davern said on NBC television’s “Today” on Friday that Wagner is to blame for the Oscar-nominated actress’ death in the chilly waters off Southern California in November 1981, but didn’t offer many specifics. For years he has maintained that he heard the famous couple arguing on the boat before Wood went missing and Wagner refusing to immediately search the waters nearby for his wife.

Davern’s account is dramatically different from what he told investigators after Wood’s body was found in 1981, when no mention of an argument between the couple was made. Wood was wearing a nightgown, wool socks and red down coat when she was found floating off Santa Catalina Island.

The renewed investigation comes at a time when plenty of attention was sure to be focused on Wood, whose beauty and acting in films such as “West Side Story” and “Rebel Without a Cause” made her Hollywood royalty. Her death stunned the world and CBS’ “48 Hours Mystery” has been looking into the case for a special airing on Saturday.

Sheriff’s officials denied the renewed attention prompted their review, which could take months.

“We’re not concerned with the anniversary date,” Corina said. “It may have jarred some other people’s memories.”

The Splendour is currently docked in Hawaii, where it’s used for charter cruises. The current owner said Friday that he was contacted by Los Angeles authorities several weeks ago. He did not reveal details of the conversation.

“I have known for a few weeks that there was going to be a police investigation,” Ron Nelson, who purchased the boat in 1986, said in an interview with KHON-TV in Honolulu. “But I didn’t know it was going to explode like it did overnight.”

Los Angeles Sheriff’s Department officials said they will travel to Hawaii to look at the boat as part of their investigation.

Davern and Wagner agree on one point about the fateful night — there was a heated argument on the yacht after the group returned from dinner on Catalina. All had been drinking, and here is where the three men’s accounts begin to differ.

Davern said he heard Wagner and Wood arguing and its outcome had horrific consequences.

Was that fight “what ultimately led to her death?” Davern was asked by “Today” show host David Gregory.

“Yes,” Davern replied.

“How so?“

“Like I said, that’s going to be up to the investigators to decide,” Davern responded after a long pause.

Wagner acknowledges a fight took place on the Splendour, but in his best-selling 2008 memoir “Pieces of My Heart,” he wrote that the fighting was between him and Walken. The disagreement began over the acting profession and led to Wood retreating to her cabin, while the dispute raged on between Wagner and Walken. Later Walken went to bed, according to Wagner, who, after staying up with Davern for a while, went looking for his wife and couldn’t find her on board. He then noticed that a dinghy attached to the boat — and his wife — was gone.

Walken, who has rarely spoken about the events that led to Wood’s death, denied in a 1982 interview on “Good Morning America” that he and Wagner quarreled.

“No, that’s not true,” Walken said when asked if a fight was the reason Wood left the yacht. “They were very good to me, that family, and that’s not true.

“We were having a Thanksgiving weekend, a good time,” he said.

But Walken told sheriff’s detectives that there was an argument, according to a 2000 Vanity Fair piece that included statements from a report by the investigating detective. It also included comments from Davern, who told the magazine that he heard Wagner and Wood fighting before she went missing.

The detective, Wagner and Walken and coroner’s officials all have maintained that Wood’s death was an accident, possibly caused by her trying to secure the dinghy to the side of the yacht.

“The people who are convinced that there was something more to it than what came out in the investigation will never be satisfied with the truth,” Walken was quoted in the Vanity Fair piece as saying during an interview in the 1980s. “Because the truth is, there is nothing more to it. It was an accident.”

Wagner too addressed the uncertainty about what happened in his book.

“Nobody knows,” he wrote. “There are only two possibilities; either she was trying to get away from the argument, or she was trying to tie the dinghy. But the bottom line is that nobody knows exactly what happened.”

Wagner said through a spokesman that his family trusts the sheriff’s department to conduct a fair investigation into Wood’s death.

The couple was married twice, first in 1957 before divorcing six years later. They remarried in 1972.

10th Ld-Writethru : Egypt police clash with protesters ahead of vote

AYA BATRAWY | AP

CAIRO: Egyptian riot police firing tear gas and rubber bullets stormed into Cairo’s Tahrir Square Saturday to dismantle a protest tent camp, setting off clashes that killed one protester, injured hundreds and raised tensions days before the first elections since Hosni Mubarak’s ouster.

The scenes of protesters fighting with black-clad police forces were reminiscent of the 18-day uprising that forced an end to Mubarak’s rule in February. Hundreds of protesters fought back, hurling stones and setting an armored police vehicle ablaze.

The violence raised fears of new unrest surrounding the parliamentary elections that are due to begin in nine days’ time. Public anger has risen over the slow pace of reforms and apparent attempts by Egypt’s ruling generals to retain power over a future civilian government.

Witnesses said the clashes began when riot police dismantled a small tent camp set up to commemorate the hundreds of protesters killed in the uprising and attacked around 200 peaceful demonstrators who had camped in the square overnight in an attempt to restart a long-term sit-in there.

“Violence breeds violence,” said Sahar Abdel-Mohsen, an engineer who joined in the protest after a call went out on Twitter urging people to come to Tahrir to defend against the police attacks. “We are tired of this and we are not leaving the square.”

Police fired rubber bullets, tear gas and beat protesters with batons, clearing the square at one point and pushing the fighting into surrounding side streets of downtown Cairo.

A 23-year-old protester died from a gunshot, said Health Ministry official Mohammed el-Sherbeni. At least 676 people were injured, he said.

Abdel-Mohsen said a friend was wounded by a rubber bullet that struck his head and that she saw another protester wounded by a pellet in his neck.

Crowds swarmed an armored police truck, rocking it back and forth and setting it ablaze. Black smoke rose over the crowd.

After nightfall, protesters swarmed back into the square in the thousands, setting tires ablaze in the street and filling the area with an acrid, black smoke screen. Police appeared to retreat to surrounding areas, leaving protesters free to retake and barricade themselves inside the square. The air was still thick with stinging tear gas.

Prime Minister Essam Sharaf urged the protesters to clear the square.

Saturday’s confrontation was one of the few since the uprising to involve police forces, which have largely stayed in the background while the military takes charge of security. There was no military presence in and around the square on Saturday.

The black-clad police were a hated symbol of Mubarak’s regime.

“The people want to topple the regime,” shouted enraged crowds, reviving the chant from the early days of the uprising. Crowds also screamed: “Riot police are thugs and thieves” and “Down with the Marshal,” referring to Field Marshal Hussein Tantawi, Egypt’s military ruler.

Some of the wounded had blood streaming down their faces and many had to be carried out of the square by fellow protesters to waiting ambulances.

Human rights activists accused police of using excessive force.

One prominent activist, Malek Mostafa, lost his right eye from a rubber bullet, said Ghada Shahbender, a member of the Egyptian Organization for Human Rights.

At least four protesters were injured in the eyes as a result of what Shahbender said were orders to target protesters’ heads.

“It is a crime,” she said. “They were shooting rubber bullets directly at the heads. ... I heard an officer ordering his soldiers to aim for the head.”

A videojournalist for the Egyptian newspaper Al-Masry Al-Youm, Ahmed Abdel-Fatah, was also hit in the eye by a rubber bullet and was undergoing surgery.

Police arrested 18 people, state TV reported, describing the protesters as rioters.

Protests were also held Saturday in Alexandria and in the Red Sea port city of Suez, where crowds tore down election posters for parliamentary candidates who were members of Mubarak’s now-dissolved party.

A day earlier, tens of thousands of Islamists and young activists had massed in Tahrir Square to protest Egypt’s ruling military council, which took control of the country after Mubarak’s ouster and has been harshly criticized for its oversight of the bumpy transition period.

Friday’s crowd, the largest in months, was mobilized by the Muslim Brotherhood and focused its anger on a document drafted by the military that spells out guiding principles for a new constitution.

Under those guidelines, the military and its budget would be shielded from civilian oversight. An early version of it also said the military would appoint 80 members of the 100-person constitutional committee — a move that would vastly diminish the new parliament’s role.

Groups across the political spectrum rejected the document, calling it an attempt by the military to perpetuate its rule past the post-Mubarak transition. Back in February, the military had promised it would return to the country to civilian rule within six months. Now, there is deep uncertainty over the timeline, and presidential elections might not be held until 2013.

Friday’s demonstration dispersed peacefully, but several hundred people remained in the square overnight in an attempt to re-establish a semi-permanent presence in the square to pressure the military council.

Violence began Saturday morning, as police moved in to clear them.

The number of protesters swelled to several thousand as news of the fighting spread in the city, and thousands more riot police streamed into Tahrir Square, blocking entrances and clashing with protesters before disappearing after nightfall.

The Interior Ministry, which runs the country’s police forces, accused people of trying to escalate tensions ahead of the parliamentary elections, which begin on Nov. 28 and will be held in stages continuing through March.

Activists say they just want to guard the outcome of their revolution.

Unemployed graduate student Nasser Ezzat said he traveled from southern Egypt to Tahrir because he wanted to help finish the revolution that people died for. He came to the square on Friday, leaving behind his a pregnant wife in the city of Sohag.

“I dream of a fairer Egypt for my unborn daughter, one without police harassment and corruption,” he said on Saturday.

Crowds also directed their anger at the police, which were the muscle behind Mubarak’s heavy handed rule.

“This violence is the same as the old regime,” activist Mona Seif said. “Police are telling us they are carrying out orders to beat us until we leave.”

Seif is the sister of prominent blogger and activist Alaa Abdel-Fattah, who is in jail after refusing to answer questions over his alleged role in sectarian clashes. He leads a campaign to end the trials of civilians in military courts.

Rights groups estimate that up to 12,000 people have been tried in military courts since Mubarak was ousted.
