Holly was 20 years old and studying to be a nurse while living at home with her family.

Holly was led into the woods, and then she vanished. It was an all-out search. Local and federal law enforcement, Holly's friends, neighbors, former classmates, and complete strangers. Thousands of local volunteers, people from all over this tight-knit community, came together to find one of their own. But Holly would never be found alive.

It would take years for her remains to be found, and what started as a missing persons case became a horrific, complicated murder investigation that would tear apart relationships between neighbors and families and change the small Tennessee community forever.

I'm ABC News Senior National Correspondent Eva Pilgrim. This story has a long history.

Before I got to ABC News in 2016, I remember hearing about it. The shocking crime, the long investigation. Reporters from across the country had made their way to Tennessee to cover it. In 2017, the case seemed to be finally closed after a guilty verdict. But years later, I was sent to Tennessee to cover new developments in a story that just keeps unraveling.

Once I got to Tennessee and started talking to people who knew Holly and who had worked on the case, I couldn't stop thinking about it. Here was a girl who was doing all the right things. She was close with her family who described her as responsible and caring, and she was studying to be a nurse. If this could happen to her, this could happen to anyone.

Usually, the more I dig into a case, the more I feel like I'm solving the puzzle. But this time, the opposite happened. As I learned more, I had more questions. How could someone just vanish from a house like hers, tucked so far away in the Tennessee woods? How could you commit a crime this brazen and get away with it for years?

When police sprung into action and so many people joined the search for Holly, how could no one find her? And after so many years, why was it so hard to find answers? I want to take you with me through the twists and turns in a case that captivated Tennessee and the nation. And let's not forget, there's a young woman at the middle of all of this.

This was a case that would leave her family and community brokenhearted and forever changed. I'll go back to the very start of the investigation on that otherwise unremarkable spring morning in 2011, and I'll walk you through the latest developments more than a decade later. Someone will be given a life sentence for Holly's murder, but that won't stop the questions for some.

Did they find the right people, or could Holly's killer still be out there?

Why speak up now? Because it's been years.
