Janet Holt, 64, has been questioned by police over her claim that she had buried the memories of the killing until she went for therapy decades later.
Her business partner Fred Handford, then 56, vanished in 1976. Despite a huge police search he was never found.
For more than 30 years Miss Holt, who worked with him at Ball Beard farm in Buxton, Derbyshire, had no clue what happened to him.
But she had repeated unexplained nightmares about Mr Handford and underwent therapy to see if there was something locked deep in her mind.
Miss Holt said the recollection was terrifyingly clear - she shot Fred after he twice raped her, then put his body in a wheelbarrow and buried him on their farm.
Police arrested and interviewed her in 2011 after she went to officers and told them where she believed she buried the body.
But after extensive searches of the 50-acre farm, he was never found and she was released.
The case remains open.
