Kara Robinson Chamberlain was just 15 years old when she was abducted by a serial killer. Now, she's searching for answers in cases that have gone unsolved for decades. The victim advocate hosts the ABC News Studios and Freeform true-crime series "Somebody Knows Something," which takes a fresh look at unsolved disappearances and murders that have baffled investigators. Working alongside loved ones, Chamberlain revisits a cold case in each episode, hoping renewed attention will generate the lead that finally cracks it. SLAIN DAD'S DAUGHTER KNEW ‘BLACK SWAN’ EX-BALLERINA SHOT HIM AFTER ONE CALL: 'SHE KILLED HIM, DIDN'T SHE?' "My purpose was to let families have the mic and show what law enforcement has done," Chamberlain told Fox News Digital. "We want people to have the information they need, so they can come forward with anything that could be helpful. Several of these cases involve children, young people. I have three kids, so I found myself identifying with either the young person who is missing or the victims themselves as parents. "I genuinely think we can make a difference," Chamberlain said. "If I can get answers for one of these families, it would be a life goal for me." That mission is deeply personal for Chamberlain, whose own story of survival began more than two decades ago. On June 24, 2002, 15-year-old Chamberlain was at a friend's home in South Carolina when Richard Evonitz, the man who would abduct her, pulled into the driveway. "There was a moment when my captor pulled into my friend's driveway, and I thought, 'That's weird,'" she recalled. "That was my intuition. But I immediately started making excuses for why he could have been there, what could have been the reason. And so, I quieted my intuition." It was a split-second instinct Chamberlain would soon wish she had trusted. FOLLOW THE FOX TRUE CRIME TEAM ON X The stranger approached her with pamphlets and asked if her parents were home. Then, he held a gun to her neck and threatened to shoot her if she screamed. He forced Chamberlain into a dark storage container in his car. "I'm often asked, 'What's the thing that we can learn from your story, Kara, to keep ourselves or our children safe?'" she said. "And the one thing that I tell people the most is there's a great book called 'The Gift of Fear.' And it's the first time that I've heard someone describe the way I feel, which is to listen to your intuition." "Essentially, what the 'Gift of Fear' describes is that we all have something inside of us that's paying attention, and we're taught to silence that intuition for the sake of being nice, not hurting someone's feelings — lots of different reasons. And that's something that is meant to keep us alive." "I hesitate to say if there's a lesson in these cases because they're all quite different," she continued. "But that's the big thing that I try to tell people — listen to your intuition and teach your children how to listen to that intuition. It is a powerful gift that everyone has, and it saves your life." At Evonitz's apartment, Chamberlain was repeatedly sexually assaulted. But this time, she trusted the instinct telling her what to do: survive. "I have to acknowledge that there was something inside of me that said, 'Not today. Not me. I'm going to outsmart this guy,'" Chamberlain said, describing herself as "very stubborn." "Then, I think really the rest of it was maybe part luck," she said. "It was also a big part of my coping mechanism ... how I chose to appease my captor, which essentially is one of the lesser-known trauma responses. It's basically playing nice to let that person put their guard down. And then, I think partially, there's this part of him that was very arrogant, and he'd done that multiple times before. So I think all of those things played together in terms of my escape." SIGN UP TO GET THE TRUE CRIME NEWSLETTER For 18 hours, Chamberlain was held captive. Throughout the ordeal, she quietly memorized as many details as she could about her surroundings. Once her captor fell asleep, she managed to free herself from her bindings and escaped. Chamberlain found people sitting in a car in a parking lot and pleaded with them to take her to police. "Anyone who learns my story ... tends to be sometimes confused by how I tell my story, which is very direct, very to the point, kind of unemotional," she explained. "And that's because my trauma response was to dissociate. ... That enabled me to get through." After arriving at a police station, Chamberlain led officers back to her captor's apartment. But when investigators arrived, Evonitz had escaped. Investigators learned Evonitz had taken Chamberlain to the apartment he shared with his wife, who was away at Walt Disney World, according to The Washington Post. Police tracked Evonitz to Sarasota, Florida. As police closed in on him, Evonitz died by suicide. He was 38. Evidence recovered from Evonitz’s apartment, former residences and vehicle linked him to the abductions and murders of three girls from Spotsylvania County, Virginia — Sofia Silva, 16; Kristin Lisk, 15; and her sister, Kati Lisk, 12. Notes discovered by investigators indicated that Evonitz already had his eye on other potential victims, Fox News Digital previously reported. GET REAL-TIME UPDATES DIRECTLY ON THE TRUE CRIME HUB Today, Chamberlain still wonders whether Evonitz had other victims. "I genuinely believe that he was responsible for more than we know of," she said. "But unfortunately, having taken his own life, that, at this point, is still a mystery." Chamberlain's own unanswered questions have also shaped how she thinks about families who are still searching for their loved ones. SIGN UP TO GET THE LATEST TRUE CRIME NEWS "I think the biggest misconception is that these families will be able to get closure one day," she said of the series. "I hear people say, 'Let's get these families closure' all the time. And at the end of the day, these people are always going to have some level of trauma. If their loved ones are recovered, they're going to look at a future where they are trying to support that person. If their loved ones are not recovered, they're never found, or unfortunately, they're found, and they're deceased, then they're looking at the rest of their lives missing someone they love." "That's the biggest thing for me, closure really is a myth," she added. LIKE WHAT YOU'RE READING?

"She would've known it because I think from very early on, I thought that I was able to handle what happened to me the way that I was able to handle it for a reason. Yes, I had this bad thing that happened to me, but that just became part of building who I became. That's not who I am. It's just a part of my story."
