Nancy Grace is leaving her post at HLN and will move to a new media venture, the cable channel's sister network CNN confirmed Thursday.

Grace will depart from the network in October, when her current contract expires.

"This fall, I'll be leaving HLN, my longtime TV home, with a full heart and endless gratitude," Grace said in a statement Thursday. "The network has been my extended family for nearly a dozen years, and I am proud of the amazing work we've produced together."

She has hosted her eponymous true crime show, one of the network's most popular programs, on HLN since 2005. Before that, she served as a legal commentator for Court TV and in Atlanta as a prosecutor -- a career she pursued after her fiancé was murdered when she was 19.

She's not leaving the media spotlight anytime soon though.

"I will continue my fight for justice across a variety of traditional and new media, where victims' voices can reach an entirely engaged audience," she said.

She elaborated a bit on her next move in an interview with The Hollywood Reporter.

"I will always be wedded to a traditional platform — which is TV, God help me," she said. "My plan is to merge those two in an effective way, in my voice, the 'anti-crime' voice. Our show has never really been about me. It has been about the stories that we tell and the people we talk about and the mysteries we try to solve and the children we try to bring home."

On Court TV and on her current show, Grace has covered major crime events and is well-known for her coverage of the Elizabeth Smart kidnapping, Duke lacrosse rape allegations and Casey Anthony murder allegations. She's faced criticism for aggressively going after suspects in those cases and painting them as guilty before they faced trial.

She's also been a vocal opponent of marijuana legalization, often twisting the facts to present it as a violence-inducing drug.
