Actor Robert Wagner is being called a person of interest in the death of his then-wife actress Natalie Wood in 1981 by police, according to CBS News.

Wagner, 87, is currently married to Jill St. John, 77. The couple has been married since 1990.

“As we've investigated the case over the last six years, I think he's more of a person of interest now,” said John Corina, a Lieutenant with Los Angeles County Sheriff’s Department in an upcoming interview for CBS’s “48 Hours.”

Wood disappeared from her family’s yacht one night in November 1981 and was found to have drowned the next day near Catalina Island off the coast of Southern California. Her death was ruled an accident at the time, but rumors and controversy have swirled around the incident ever since.

Los Angeles County investigators reopened the case in 2011, and the city’s coroner changed the woman’s cause of death to “drowning and other determined factors,” in 2012.

On the boat when Wood died were Wagner, boat captain Dennis Davern and actor Christopher Walken.

“When Natalie died I thought my life was over. Natalie was such a special, wonderful woman,” said Wagner in an interview with Express last year.

Wagner and St. John, who had known each other since the 1950s, began dating a few months after Wood's death.

St. John was born Jill Arlyn Oppenheim in Los Angeles in 1940. She first started out as a radio actor at the age of 6 and made her screen debut at nine in a television-movie adaptation of “A Christmas Carol.” Her major film debut was in 1958’s “Summer Love.”

St. John garnered a Golden Globe nomination for her role in 1963’s “Come Blow Your Horn.” She was also the first American to play a “Bond Girl.” She starred as Tiffany Case opposite Sean Connery who played James Bond in 1971’s “Diamonds are Forever.”

Wagner is St. John’s fourth husband. She married Neil Dubin in 1957, but they divorced the next year. She then married Lance Reventlow in 1960 and they divorced in 1963. She married Jack Jones in 1967 and they divorced two years later.

St. John is also the author of a cookbook “The Jill St. John Cookbook,” published in 1987.
