This is Deborah Roberts. You're about to hear what happened to Holly Bobo. In this series, ABC News's Eva Pilgrim will take you through the twists and turns of a murder case that captivated Tennessee and the nation. Here's episode one.

On Saturday, April 9th, 2011, Tennessee's wildflowers were in full bloom. Its rolling hills were a vibrant green,

and that weekend, winter seemed long gone as temperatures soared into the 80s. It was the perfect

setting for one of the most beloved traditions in western Tennessee, the annual raccoon hunt

in Decatur County. The hunt dates back to

1976 and is billed as the largest in the world. Throughout the weekend, dogs chase after

raccoons and are rated on their performance, including how fast they can track down the raccoons.

The winning dogs and their owners get prize money, which is donated to St. Jude Children's Hospital.

There are country and bluegrass performances,

auctions, and lots of local food vendors serving barbecue and pies.

Every April, thousands gather at the county fairgrounds for the hunt.

the quiet community on the banks of the Tennessee River,

The caller was Karen Bobo.

They lived on quiet Swan Johnson Road for decades in a home tucked away in the woods.

Hey, what's your daughter's name, Ms. Karen?
