The programme, which will look into how Kim and her boyfriend Lucas stabbed both her mum and younger sister as they slept in April last year, will be aired on Channel 5 at 9pm.

Elizabeth Edwards and her daughter Katie were murdered by the two teenagers at their home in Spalding

It will look into how the young couple, who were both 14 at the time of the murders, planned the killings weeks in advance.

Both have been sentenced to a minimum of 20 years in prison.
