A 15-year-old girl butchered her mum and younger sister to death alongside her boyfriend because her mum ‘liked her sister more’, she revealled in a chilling police interview.
Kim Edwards, who is believed to be one of Britain’s youngest double murderers, and Lucas Markham ‘brutally executed’ dinner lady Elizabeth Edwards, 49, and her daughter Katie.
The murders took place as Elizabeth and the 13-year-old slept at their home in Spalding, Lincolnshire last April.
In an interview, which has today been released, Kim said she planned the killings through ‘general knowledge’.
And that her motive was that her mum ‘favoured my sister more than me’.
After the double murder, Edwards and Markham, likened to Bonnie and Clyde during their trial, had sex, shared a bath and watched four Twilight vampire films.
The identities of the couple could not be reported throughout a trial at Nottingham Crown Court in 2016 because of their age, but restrictions on naming the pair were lifted by three judges at London’s Court of Appeal.
Footage from the interview also revealed that the 15-year-old ‘did not regret the killings’.
She said that she had ‘made peace’ with the deaths because ‘it wasn’t like torture or anything’.
She said: ‘Just, the fact that it happened so quickly gave me piece of mind.’
When asked if she was happy that her mother and sister were dead, the teenager said ‘Yes, in a way’.
She said: ‘Yes, because my mum doesn’t have to deal with me anymore, being like, you know, suicidal, and she doesn’t have to wake up worrying every morning to see if I’m still alive.
‘And my sister doesn’t have to go through all the heartbreak and all the emotions and stuff.’
The young pair, dubbed the Twilight Killers, were both originally given 20-year minimum custodial terms.
They, however, had them reduced by the judges to 17 and a half years each.
Teenage killer Kim Edwards was found by police lying under a duvet in front of the TV with Lucas Markham as the bodies of her mother and younger sister lay upstairs.
She told police she had had a bath because she ‘didn’t want the dog to smell the blood’.
Full transcript of Kim Edwards’ interview
‘I thought I heard her say get off me but I’m not entirely sure. Then after about 10 minutes of Lucas putting his weight on her, erm, like, she was dead.’
Interviewer 1: ‘What exactly happened to cause you to want to plan this?’
Kim: ‘Erm, well, I don’t know really, it just kind of happened’.
Interviewer 1: ‘I mean it’s clearly quite a drastic thing to happen, you clearly – from what you’re saying – had your reasons. I mean, what were those reasons?
Kim: ‘Erm, just that, ever since I was young I have never got on with my mum. I knew that she favoured my sister more than me. Erm, even though that she said she didn’t I knew that she was lying’.
Interviewer 1: ‘And how did you feel?’
Kim: ‘Erm, I was OK with it. Just, the fact that it happened so quickly gave me piece of mind. Because it wasn’t like torture or anything.’
Interviewer 1: ‘And how do you feel about it all on reflection now?’
Kim: ‘Erm, the same way.’
Interviewer 1: ‘What, relieved that it’s done?’
Interviewer 1: ‘You feel happy about it?’
Kim: ‘Erm, to a point, yes.’
Interviewer 1: ‘Why is that?’
Kim: ‘Yes, because my mum doesn’t have to deal with me anymore, being like, you know, suicidal, and she doesn’t have to wake up worrying every morning to see if I’m still alive. And my sister doesn’t have to go through all the heartbreak and all the emotions and stuff.’
Interviewer 2: ‘Where did you think up to kill your family? To do it via a knife? To stab them in the throat? Have a bath afterwards? To commit suicide afterwards? Where does all this come from? Have you seen something like it? Have you read something like it?’
Kim: ‘No, not really. We just went with general knowledge really. Cause the voice box, stabbing the throat, the bath cause of the dog – so she wouldn’t smell the blood. Lucas I don’t like the smell of blood. Erm, just yeah, and committing suicide after was just cause most people who do commit murders do try and commit suicide themselves.’
Interviewer 2: ‘So there was nothing that you had seen, you had read, that gave you this sort of notion? Nobody had discussed it with you? It was just you and Lucas?’
Interviewer 2: ‘I’m sure you realise at this stage just how serious this is, don’t you? I mean you’re a very young girl but this is very, very serious for you and Lucas. So if there is anything you need to tell us, you might as well get it off your chest now.’
‘I appreciate the fact that you have told us what you told us, but if you have anything lurking that you didn’t say, you might want to get that clear?’
Kim: ‘Erm, no.’
