The two Spalding teenagers who became Britain’s youngest double murderers will be detained for at least 20 years each.
The boy and girl were just 14 at the time they killed Spalding dinner lady Liz Edwards (49) and her daughter Katie (13).
Both are now 15 and were ordered to be detained at her majesty’s pleasure with a minimum tariff of 20 years each.
The boy admitted two charges of murder and the girl was found guilty by a jury of the same two charges of murder. She admitted manslaughter by reason of diminished responsibility but denied murder.
Mr Justice Haddon-Cave, passing sentence at Nottingham Crown Court this afternoon (Thursday), described the killings as “brutal executions”
He told the teenage defendants “Had you been adults you may well have been facing the whole of your lives in prison for these terrible murders.
both victims, particularly Elizabeth Edwards, must have suffered terribly in the last minutes of their livesMr Justice Haddon-Cave
“There was remarkable pre-meditation and planning.
“The killings were brutal in the form of executions and both victims, particularly Elizabeth Edwards, must have suffered terribly in the last minutes of their lives.
“People who know the full facts of this case may struggle to comprehend how you both could commit this terrible and unnatural crime which has devastated families and a community.
“The answer lies perhaps in what the psychiatrist described as your toxic relationship.
“You were in a hermetically sealed world of your own of deep, deep selfishness where only your feelings mattered and nobody else’s.
“This was an entirely joint offence. You were in it together from the beginning.
“You conceived the killings together, you planned it together, you replanned it together and carried it out together step by step.”
