(Photos) Mother killed by her 14 year old daughter and boyfriend who had sex after the murder

A dinner lady stabbed to death in her bed was killed by her teenage daughter and her boyfriend, it can be revealed for the first time today.
Elizabeth Edwards, 49, and 13-year-old daughter Katie were murdered as they slept at their home in Spalding, Lincolnshire in April last year.
It has now been reported today that their killers were Ms Edwards' own daughter, Kim, and her boyfriend, Lucas Markham, who were both 14 at the time, and their crime was motivated by petty jealousy.

According to Daily Mail, after the killings, the couple, likened to Bonnie and Clyde during their trial, spent the next 36 hours in the house where they had sex, shared a bath, ate tea cakes and ice cream and watched four Twilight vampire films.

The teenagers were jailed for murder for a minimum of 20 years in November for what a judge described as the 'executions' but could not be named for legal reasons.

After the press spent eight months pushing for their identities to be revealed, restrictions on naming the pair were lifted by three judges at London's Court of Appeal today and the full, harrowing facts of the case can now finally be reported.

Appeal judges also reduced their sentences to life with a shorter minimum tariff behind bars of 17-and-a-half years.
