Spalding teenage killers to be sentenced this week

A 15-year-old boy pleaded guilty to the murders of school dinner lady Elizabeth Edwards (39) and her daughter Katie (13) in April this year.

A 15-year-old girl was found guilty of the double murder after a five-day trial. She had admitted manslaughter but denied murder, claiming that mental illness had diminished her responsibility.

The victims had been stabbed through the throat and smothered.

The teenagers – thought to be Britain’s youngest ever couple to be convicted of murder – went on to share a bath, have sex and watched four vampire-themed Twilight films after the murders in Dawson Avenue, Spalding.

They will be sentenced by Justice Haddon-Cave.
