At first glance, it looked like 40-year-old, Shannon Hercutt's death was an accident in 2009. In fact, that's what the Sevier County Sheriff's office first called it.
Reports showed On August 3, 2009, police responded to an OnStar alert of a car crash. Inside of a Cadillac SUV, at the bottom of a steep slope, they found the Shannon's body.
Just days after police ruled it an accident, officials said they believe someone actually killed the successful realtor in her home, placed her body in her vehicle and sent it down a hill.
Suspicion grew in the Hercutt family and months after Shannon's death her sister, Penny and step mother appeared on the Dr. Phil show to confront Shannon's Dad, Ted Hercutt.
"I know you have paid someone to kill Shannon. Don't sit there and act like you're so innocent," Shannon's sister, Penny said to their father.
Ted Hercutt said then he did nothing to his daughter.
He was never charged and he died in November 2017.
While some family members insist Ted Hercutt had something to do with the murder, the Sevier County Sheriff's Office never found evidence of that.
We reached out to Penny on Friday, exactly nine years after her sister was killed.
"It seems like it was only yesterday that I got the call that my sister was dead. I still wake up thinking it's just a nightmare," Penny said.
Two years ago, Penny moved out of Tennessee searching for a fresh start, but while her surroundings change she said her life goal will not.
"My life goal is to get Justice for my sister! I can't rest or go on until I do," Penny said.
Investigators said the case remains under investigation. If you have any information that could help crack it, please call the Sevier County Sheriff's Office.
The Hercutt family said a $45,000 reward is still available for information leading to the arrest and conviction of whoever killed Shannon.
