Channel 4 News has learned the investigation into the disappearance of a woman last seen being led away from her Parsons home weeks ago is now drawing other cases of missing and slain women in the same area.
Investigators are considering cases involving at least four women who were abducted back to 1980.
In 1980, two teenage girls walked to a store in Dover. They bought their items, began the one-mile walk home and were not seen again.
Six weeks later, 14-year-old Carla Atkins and 16-year-old Vicky Stout were found dead. They had been executed in a remote area of Land Between the Lakes.
Thirty years later, the crime is still unsolved. Abner Vires was the deputy who found the bodies. Now retired, 73-year-old Vires still can't let it go.
"I feel like I had a job at that time to do," he said. "It was just one of them things that stayed on my mind and just couldn't get it gone."
In Dickson County in 1987, 18-year-old Leanne Greene and her brother ran out of gas. Her brother jogged to a gas station. He returned 8 1/2 minutes later to find his sister gone. She's still missing.
When a serial killer from Florida named Robert Richards confessed to the crime and was then killed in prison, the FBI closed the case. Leanne's family said they never believed that Richards had anything to do with it, and he couldn't tell police where the body was.
"It's like being in a maze, and you turn to one and hit a dead end and turn to another and hit a dead end," said Laurie Green, the victim's sister.
In 1992, Shelia Bradford went to the Tennessee Bureau of Investigation. She had some information about a man she knew. Two days later, she disappeared; 18 years later, there's still no body and no clues.
"Nothing was knocked over. There was no sign of struggle -- just like she had flushed herself down the commode and was gone," said Kristie Downing, the victim's daughter.
All of the disappearances were within an hour's drive of each other.
Downing said she knows what missing woman Holly Bobo's parents are going through; not one day passes that she doesn't miss her mom.
"My heart hurts for them. I want to go down there and help. It's hard for me to take part in something else; it just becomes very emotional for me. I want her to be found; I want her to be OK," said Downing.
