Kara Robinson Chamberlain, who survived abduction by serial killer Richard Evonitz when she was 15, now hosts the true-crime series "Somebody Knows Something." The show revisits unsolved disappearances and murders, aiming to generate new leads by giving a platform to victims' families and investigators.

"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."

Chamberlain's own survival story began on June 24, 2002, in South Carolina. While at a friend's home, Evonitz approached her, initially with pamphlets, before threatening her with a gun and forcing her into a storage container in his car. Chamberlain recounted a brief moment of hesitation before dismissing an instinct that something was wrong.

"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."

During her 18 hours of captivity in Evonitz's apartment, Chamberlain endured sexual assault. She credits her survival to a combination of her own resilience, a degree of luck, and a coping mechanism of appeasing her captor to lower his guard. She also noted Evonitz's arrogance, stemming from previous successful abductions.

"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."

When Evonitz fell asleep, Chamberlain freed herself and escaped. She found people in a parking lot who took her to the police. At the station, she provided information that led investigators to Evonitz's apartment. However, Evonitz had already fled.

Evidence found at Evonitz's residence and other locations linked him to the murders of three teenage girls in Virginia: Sofia Silva, 16; Kristin Lisk, 15; and her sister, Kati Lisk, 12. Investigators also found notes indicating Evonitz had targeted other potential victims. Evonitz died by suicide in Sarasota, Florida, on June 27, 2002, after a police pursuit.

Chamberlain believes Evonitz was responsible for more crimes than identified, but his death has left those questions unanswered.

"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."

In her series, Chamberlain aims to offer a different perspective on the concept of closure for victims' families.

"I think the biggest misconception is that these families will be able to get closure one day," she said. "That's the biggest thing for me, closure really is a myth."

Chamberlain completed training at the South Carolina Criminal Justice Academy in 2010 and worked for the Richland County Sheriff's Department as a school resource officer, sex crimes and child abuse investigator, and victim advocate. She now uses her experiences to help other families seeking answers.
