In episode five of Britain's Darkest Taboos, viewers will learn about the murder of Rana Faruqui who, at the age of 35 was stalked and murdered in cold blood by an ex-partner.
We got the opportunity to chat to Rana's sister Gemma about the horrific crime, her worries when the murderer is due for parole in 2017 and more.
Can you tell us a little bit about your sister Rana and what type of woman she was?
Rana was 11 and a half years older than me. We had a close relationship that became closer as I got older. She was a feisty woman who loved her horses. She was independent, strong and fun loving, but vulnerable when our Dad died in April 2002, as she was a Daddy's girl.
Rana was murdered by ex-partner Stephen Griffiths - do you remember the first time you met him and if so, what were your first impressions of him?
I met him at the end of 2002 when she had just started seeing him. She wasn't sure about him but wanted to give it a try. I thought he was a bit strange but there was nothing I could put my finger on. Personally, I didn't think it would last.
He stalked Rana after their relationship had ended - did she ever confide in you about this and what sort of things did she tell you he would do?
She told me that he had been seen by a neighbour loitering outside her house. He was also at a horse event taking photos of her. She also told me that he emailed and texted her several times a day. She wasn't scared of him - she just found him annoying and irritating. Two weeks before he killed her, the brakes were cut on her car. She was sure it was him.
Griffiths is eligible for parole next year - what are your worries with his potential release?
We are obviously worried for our safety and that of our family but we are convinced that he is a danger to women and he will offend again. No woman who meets him is safe.
How do you feel the justice system worked, or perhaps failed you in this case despite Griffiths getting a 'life' sentence?
A life sentence doesn't mean life - the fact that he has killed someone and could potentially be out of jail in 14 years is sickening. 'Life' should mean life! The justice system failed us. We have a life sentence and will never see Rana again but he could come out of jail and start living his life again. Where is the justice in that?
What sort of impact has Rana's death had on your life in the past 12 and a half years?
I miss Rana every day. She has missed my wedding and being involved in my children's lives. She'll never see them grow up, watch them learn how to ride their pony. She was my friend as well as my sister so I miss going for a drink with her or a chatty email. She had so much to live for and her life was cut short by someone who was so insignificant in her life. I see how her death has affected my mother and brother as well as myself - we all miss her and all the positive major events in our lives are bittersweet as she is not there to share them with us.
