DICKSON, Tenn. (WTVF) — April 15 marks 35 years since Martha Leanne Green disappeared near Dickson. The 17-year-old, who went by Leanne, was last seen on Highway 46 near Fabric Road.

According to the Dickson County Sheriff's Office, Leanne was picked up from her job at the Holiday Inn by her twin brother. While on their way home, they ran out of gas.

A family coming home from church stopped to help them and took her brother to a nearby gas station. Leanne decided to stay in the car, but after about ten minutes they came back and she was gone. Her purse and wallet were still in the car, as well as the car keys, and there was no sign of a struggle.

Leanne was a junior at Dickson County High School and was planning to go to prom the following night. Her pink prom dress and shoes were on the bed at her home the night she disappeared.

The search was launched by the Dickson County Sheriff's Office. It grew into a large investigation involving multiple agencies including the Tennessee Bureau of Investigation and the FBI. Hundreds of searches have happened as well as interviews.

A Florida inmate, Robert Richards, confessed to murdering Leanne, but no evidence connected him to the scene. He was never charged, and was later stabbed to death in his prison cell.
