Robert Wagner is still not thought to be an official suspect in the death of his wife Natalie Wood, though the Hart To Hart star has "declined to be interviewed" by police re-investigating the strange drowning of the Hollywood star. The body of the actress was found a mile away from the yacht she had been aboard with Wagner and Christopher Walken in California, 1981, reports BBC News.

Wood's death was also presumed to be a tragic accident, though the case was reopened in 2011 when the yacht's captain Dennis Davern told various American television shows that he heard the Hollywood couple arguing on the night of her disappearance. Though Wagner suggested she could have slipped into the water after reaching overboard to tie down a lifeboat, Wood was known to be terrified by water. The actor's solicitor Blair Berk said Wagner had nothing to hide, "Mr Wagner has fully co-operated over the last 30 years in the investigation of the accidental drowning of his wife in 1981. He has been interviewed on multiple occasions by the Los Angeles sheriff's department and answered every single question asked of him by detectives during those interviews," read a statement. Earlier this week, coroner's officials released an updated autopsy report which reclassified the death from accidental drowning to drowning caused by "undetermined factors." Investigators are looking into bruises and marks found on Wood's body.

Lieutenant John Corina of the Los Angeles County Sheriff's office claimed detectives tried to interview Wagner on more than 10 occasions, but had been turned down each time. He said: "Most of the people we've talked to were never talked to 30 years ago. We've got a lot of new information."
