Natalie Wood death: Police say Robert Wagner 'person of interest' http://www.bbc.co.uk/news/world-us-canada-42911769 US police investigating the mysterious death of film star Natalie Wood say her husband Robert Wagner is now a person of interest. Investigators in Los Angeles say Wagner has "constantly changed his story", adding that his version of events does not "add up". Wood was found drowned in 1981 during a California boat trip with Wagner and the actor Christopher Walken. Her death was ruled to have been an accident but questions have lingered. "As we've investigated the case over the last six years, I think [Wagner] is more of a person of interest now," Lt John Corina of the Los Angeles County Sheriff's office told CBS News. "We know now that he was the last person to be with Natalie before she disappeared," he said. "I haven't seen him tell the details that match all the other witnesses in this case". "I think he's constantly changed his story a little bit. And his version of events just don't add up," Lt Corina added.
