Shafilea Ahmed's sister's told a court her death had haunted her and she talked to police because she felt she was being forced down the same path with an arranged marriage.
Alesha Ahmed says she got three men to stage a robbery at the family home in Warrington in 2010 when her parents wouldn't give her money for University. She said she
"snapped. It was just hard living the way they wanted me to, or living on my own. Both were a struggle"
She was arrested after the robbery and has pleaded guilty. Soon after she gave a statement to police saying her mother and father murdered Shafilea by suffocating her in 2003.
Iftikhar and Farzana Ahmed deny murder. When questioned about why she has made the claim after all these years she siad:
"I think at that point I was really suffering with the family (and) the build-up to the robbery.
"It all got too much, and to be honest I think it was a relief more than anything to be able to tell someone finally."
"I think it was not until I went to uni I saw how wrong family life was.
"When you get used to something, it becomes normal and that's when I saw it wasn't normal, really.
"I think what happened to my sister was wrong but because it's your parents you think it's normal because you still love them.
"I think at uni I did feel the way my sister had - you want to fit in with everyone else but you are still being forced to live in a different way.
"I think that's what made me crack."
