He was found murdered on New Year’s Day in 2003.
More than five years later, there's no suspect and no clear motive in the shooting death of a Tennessee man in Bell County.
Police are asking for your help in finding Aaron Simpson’s killer in this week's edition of Mountain Cold Case.
Anna Lee Brock has been through a lot in the last few years.
Her son Amon "Cotton" Brock was one of five men who died in the Darby Mine Accident in 2006.
Three years before that her brother, 53-year-old Aaron Simpson, was found murdered inside this truck.
Two people on a four wheeler made the gruesome discovery on this gravel road just off US 25E in the Fourmile area of Bell County.
Brock says her brother was shot through one of his eyes.
“He was laying in the truck with his feet hanging out the passenger side,” says Anna Lee Brock.
Brock says she hadn't seen her brother recently before he was killed. He was living in Thorn Hill, Tennessee.
“He did a lot of trading with people in Bell County. He lived there for 30 some years,” says Brock.
Simpson’s wife told Brock he was in Bell County to get a haircut. Brock says she doesn't know any specific reason why someone would want to kill him.
“He did have a bad temper now. He was high tempered like myself,” says Brock.
Police say they have no suspects, and no motive for Simpson’s murder.
They won't say if he was robbed, but believe he was killed on New Year’s Eve. They're also looking for a specific vehicle.
“It's believed that it's possibly a maroon Chevy Astrovan that was involved,” says Walt Meachum, Kentucky State Police.
Police say the case is still open and they will follow-up on any new leads they receive.
Anna Lee Brock just wants to know who killed her brother.
“I'd love to see the man that did it brought to justice and get some time in jail,” says Brock.
