Twilight killer girl’s friend reveals teen loved Oreos and pop hits… but ‘violent’ boyfriend transformed her into brutal murderer

BRITAIN’S youngest female double-killer was a music-obsessed teen who was addicted to Oreo cookies, her best pal has revealed.

In an interview with The Sun on Sunday, the friend told how her former mate changed after meeting her boyfriend.

Just months later the pair murdered school dinner lady Elizabeth Edwards, 49, and her youngest daughter Katie, 13.

They were butchered with a 8in kitchen knife as they slept in their beds.

After the “grudge” killings the pair — then 14 — had sex, watched Twilight films and ate ice cream.

But the murderer’s friend, 15, said: “The girl I first knew could never have done something so appalling.

“She was sensitive, kind and wanted to become an artist.

“She loved Oreo cookies and wore stick-on nails so she would appear more grown up.

“We used to spend our Saturday afternoons shopping in New Look and trying out the make-up testers in Superdrug.

“She loved pop music and her favourite song was Waterfalls by TLC.

“I like One Direction, The Vamps and Olly Murs. We always used to have a mini-argument about it.”

But she said her once carefree pal became increasingly distant after meeting her partner in crime.

She said: “She changed when she got her boyfriend. I think he was her first one.

“I didn’t used to talk to him. But he used to send horrible messages to other people she was friends with.

“He was controlling and towards the end she was very distant and not the person I first made friends with at all.”

The girls first met two years ago when they began studying GCSEs and just “clicked”.

The pal said: “We once had a mini picnic in science — we were in the naughty class, everyone would mess around.

“We would eat Oreos in the class. She was funny, happy-go-lucky and loved jokes.

“We used to make up dance routines in science to songs we made up in our head.”

Their last class together was a science lesson on April 13.

They chatted, made up songs and munched on Oreo biscuits.

After school they hugged and said goodbye before going their separate ways.

Hours later the murderers killed Elizabeth and Katie in their beds in Spalding, Lincs, after plotting it for days.

They were arrested when cops found the bodies 36 hours later. Nottingham crown court was told the killers had a “Bonnie and Clyde” mentality.

But when the girl murderer’s best friend went to school the next day, she could never have contemplated what her “calm” pal had done.

The teenager said: “I turned up and she wasn’t in her seat. She was always at school so I thought it was odd.
“I then heard something bad had happened. I haven’t heard from her since. No one has.”

Detectives are still struggling to understand the motives for the astonishing savagery inflicted on church-going Elizabeth and Katie.

The pal’s mum said her daughter is also struggling to accept that her smartly dressed, polite, kind, fun friend could in fact be a killer.

Her parents now plan to take her for counselling.

But the teen has happier memories of when she and her friend would go on shopping trips together to Spalding’s Springfields retail park.

She said: “We would always go to the American sweet store in the shopping centre to buy gobstoppers and Oreos.

“She even had a pet chinchilla she called Oreo — but it got squashed under the sofa.

“We used to go in all the shops, apart from Bonmarché, because that’s for old people.

“She loved shopping and fashion. New Look was her favourite. We also used to buy fake, stick-on nails and put them on with glue.

“In Superdrug we would cover our hands in the bright eye shadows to test out the colours.

“She used to get given £10 but I used to bring £20 or £30 and we used to pool all our money together and buy our shopping.”

The pair would end their shopping trips with a visit to McDonald’s — where they would buy their favourite Oreo McFlurrys.

But despite their closeness there were glaring differences in their personalities.

The pal said: “We used to go to Claire’s Accessories and buy nail varnishes.

“But she would go for black or dark colours whereas I liked pink.

“She wasn’t into the music I was into. She liked Years & Years and Lukas Graham, who sang Seven Years Old.

“I used to have her singing it in my ear all the time.

“It used to get on my nerves because it always got stuck in my head, but she loved it.”

But after the killer met her boyfriend, the time the friends spent together away from school dwindled.

They would only go on shopping trips if she “wasn’t busy with her boyfriend”.

And although they both liked the Twilight films, the friend said they never watched them together — and had never even been to the cinema with each other.

But despite everything that has happened, the pal still feels sad that her friend will never get her art exam results. She said: “She was really good at painting.

“We were doing a picture for our final assessment piece and she painted a flying horse with wings. It was very good but she will never find out her grade now because of what has happened.

“She might have wanted to be an artist when she left school because that was something she really enjoyed.

“We hoped to buy a house in Spalding together and used to talk about it in ­science. That won’t happen now. It’s hard to believe that she did this. She’s lost her life too. It’s just sad.”

The killers, now aged 15, are due to be sentenced on November 10.

The boy admitted murder. The girl denied murder and admitted manslaughter on the grounds of diminished responsibility.

But she was convicted of murder on Tuesday following a six-day trial.
