That is where Barnes would assault Becky, up to three times a week, for the next two years.
“I always had an incling it was wrong,” Becky said.
“I wanted to tell someone, and so many times I went to approach a teacher at school – but I just couldn’t.
“I didn’t feel good about myself at all.”
Becky was removed from the Barnes’ household shortly after her sixth birthday, when she was fostered by her uncle.
She remained in the care system and would often get in trouble with the police, after becoming a ‘rebellious child’.
From as young as seven, Becky suffered with mental ill-health and regularly attended counselling sessions.
She remained in the care system until the age of 21.
Becky says she has found it hard to settle as a result of her ordeal.
The abuse Barnes inflicted on her remained a secret for 21 years until she finally told her mother.
“As soon as my mother found about it she rang the police,” Becky said.
“The police called me and asked me if I wanted to formally report it, but I couldn’t at first because I didn’t want it out there in the open.
“You see it all the time where men and women like that just get away with it.
“I never thought he’d actually be punished for what he did to me.”
Becky’s mum persuaded her to come forward, and in May 2017, she formally made an allegation to GMP.
She provided police with a video interview and Barnes was arrested later that evening.
He continued to deny his crimes and elected to go to trial at Manchester Crown Court.
Becky was subsequently forced to take to the witness stand and recall the horrific events to a room full of strangers.
“It was so scary, but it needed to be done,” Becky said.
“It was difficult for me as I was asked to look at photos from that shed – the shed I hadn’t seen since I was six.”
The jury believed her story.
Now Kenneth Barnes will serve a lengthy prison sentence and remain on the sex offender register for life.
Becky, who now lives with her partner Claire and her three young children, says that her faith in the criminal justice system has been restored. She is now calling for other victims to come forward.
“I just want other victims to come forward and report what has happened to them,” she added.
“I hope my case proves sexual assault victims can come forward and get justice
“A lot of people feel with historic cases that it’s not going to go anywhere, but my case proves that it can.”
