In November 2014, 21-year-old Fri Martin killed her childhood sweetheart and the father of her children, Kyle Farrell, following an argument in her kitchen in Toxteth, Liverpool. At her trial six months later, Fri claimed she was acting in self-defence. According to her, Kyle had attempted to strangle her before she picked up a kitchen knife and stabbed him in the heart. But the jury unanimously convicted Fri of murder, and she was sentenced to life in prison with a minimum term of 13 years.

Now she is appealing her conviction, but Kyle’s family want her to stay behind bars.
