TEENAGE lovers who are believed to be Britain’s youngest double-murderers have each been locked up for at least 20 years after killing an Edinburgh mother and her daughter.
The boy and girl - both 14 at the time of the murders - planned the killings of 49-year-old Elizabeth Edwards, originally from Edinburgh, and 13-year-old Katie who were stabbed through the throat and smothered as they slept.
The teenagers, now 15, went on to share a bath, have sex, and watch four Twilight vampire films after the murders in Spalding, Lincolnshire, last April, Nottingham Crown Court heard.
Sentencing the pair, who cannot be named for legal reasons, to life with 20-year minimum terms, Mr Justice Haddon-Cave said: “This case is, in many respects, without parallel.”
The judge said the case had “defining and particularly chilling” features, including the young age of the defendants and that the offence was carefully planned.
As both teenagers remained composed in the dock, flanked by security guards, the judge condemned their conduct after the killings as “grotesque”.
He told the teenagers: “This is a case of double murder. One of the victims was a young girl. There is a clear intention to kill both victims - both defendants admitted wanting to murder them.
“There was remarkable premeditation and planning - it was, on any view, substantial, meticulous and repeated.
“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.”
