American actor Robert Wagner has declined to be interviewed by detectives in a renewed inquiry into the drowning death of his wife Natalie Wood three decades ago, US investigators say.
Wagner was interviewed by authorities soon after Wood's drowning in 1981, but he is the only person who was on the yacht the night Wood died who has not spoken to detectives as part of the latest inquiry, despite repeated requests and attempts.
Blair Berk, an attorney for Wagner and his family, said the actor had cooperated with authorities since his wife died.
Detectives began re-investigating the case in November 2011.
Since then investigators have interviewed more than 100 people, but Wagner has refused and Corina said the actor's representatives have not given any reason for his silence.
The detective's remarks provided new insight into the case that has remained one of Hollywood's enduring mysteries.
Earlier this week, coroner's officials released an updated autopsy report that had been under a security hold.
It detailed why Wood's death had been reclassified from an accidental drowning to a drowning caused by "undetermined factors."
"Mr. Wagner has fully cooperated over the last 30 years in the investigation of the accidental drowning of his wife in 1981," Berk said in a prepared statement.
"Mr Wagner 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."
After 30 years, Berk said, neither Wagner nor his daughters have any new information to add. She said the latest investigation was prompted by people seeking to exploit and sensationalise the 30th anniversary of the death.
