Drama has followed West Side Story star Natalie Wood's daughter Courtney Wagner since Natalie's death in 1981. And the tumult shows no signs of stopping now that Natalie's husband and Courtney's father, Austin Powers actor Robert Wagner, has been named a person of interest in the tragedy. Courtney is the only biological child of the two Hollywood stars, but she hasn't spoken out about the investigation into her father.

In 2012, Courtney told FOX411 about the aftermath of that fateful night. "I remember waking up to my sister [Natasha Gregson Wagner, Natalie's daughter with Richard Gregson] screaming, and luckily I had a nanny that I was very close to that was by my side," she said. "There were all these people in the living room, and my dad told me I wasn't going to see my mom again. I was just trying to make sense of it, and Dad was asking if we wanted to go and see her one last time."

Courtney hit another rough patch earlier in 2012, when she was arrested for cocaine and heroin possession at her home in Malibu, CA, after cops responded to reports of screaming and the sound of a gunshot, as TMZ reported at the time.

"A label was put on me, and I felt so badly that my mom was associated with having a so-called 'junkie daughter,'" she told FOX411. "I was so upset that I had defamed her name, and I had to look at how I could make this better for my mom and find healthier ways to deal with everything that has happened to me."

Now 44, Courtney is a jewelry designer whose celebrity clients include Cameron Diaz and Ozzy Osbourne, as Courtney said in a 2015 appearance on Wendy Feldman's online radio show. She also told Wendy she was "in a very good place" and felt like she was "41 going on 14."

But Courtney has dropped off the radar since, especially because she avoids social media. "I'm so glad that wasn't around when we went through [Natalie's death] as a family," she told Wendy in 2015.

Her lack of social media presence, however, means we don't know how she's contending with the renewed speculation her father had something to do with her mother's death. But she'd probably take his side, if her FOX411 interview is any indication. "There are certain people in our lives that continue to drudge up all this speculation and stories every year for no other reason than to indulge themselves," she said at the time.
