A young mum fascinated by murder and male sacrifice stabbed a teenager five times after persuading him to cover his face with a pillow before sex, a court heard.

Kieran Bewick told the Carlisle Crown Court how moments before Zoe Adams plunged a 10-inch blade into his torso, she said: 'Trust me.'

Adams sat quietly in the dock as the 18-year-old gave his harrowing account of events that led to him being stabbed in Wigton on July 29 last year.

The 19-year-old defendant admitted to intentionally causing him grievous bodily harm, but insisted Mr Bewick's story was made up.

Zoe Adams was fascinated by murder and male sacrifice and stabbed a teenager five times after persuading him to cover his face with a pillow before sex, a court heard.

Lawyers watched the videotaped interview with Mr Bewick as the auburn-haired Adams looked on wearing a white tiger-print blouse.

He said the pair went shopping in Carlisle then went back to Adams' home in Brindlefield, where they drank alcohol and she also smoked marijuana.

He drank so much he threw up. About 8.30pm, he was in bed when Adams came upstairs, her face covered in clown makeup and asked if it scared him.

'She walked in with her hands behind her back,' said Mr Bewick. 'And asked: 'Does this scare you?' I said: 'No - go and wash it off.''

The day before, he said, they had exchanged messages about clowns, and he told her that a barefoot clown was his nightmare.

He said her reply to that was: 'A barefoot clown, the ultimate Kieran killer.'

Mr Bewick was convinced she had the knife behind her back as she came upstairs made up as a clown and expected him to be asleep, and he believed she wanted to stab him then.

He also recalled a text message from her on June 9, saying that her sexual fantasy was a male tied up, and used as a human sacrifice.

A friend posted this shot to Facebook six months before the stabbing saying she looked a 'little too excited' to be cutting open a heart in science class

Half an hour after she confronted him with clown makeup, she asked him downstairs whether she could tie him to the bed, but he said no.

He went back to bed, and at 10pm she came into the room, this time carrying duct tape. Again, she again asked to tie him to the bed, and again he refused.

They then began kissing, and she asked him to put a pillow over his head, saying: 'Cos it's kinkier that way.' He said as a compromise he agreed.

His phone then went off and she grabbed it, putting it beside the bed. She then asked him: 'Do you really love me?' Then she asked 'Do you really want me?'

He answered yes, after which Adams told him: 'Put the pillow back over your face - trust me.'

So he did as she asked. That was when she stabbed him, Mr Bewick told the police officer interviewing him.

'The next thing I knew she stabbed me,' he said.

'It took me a few seconds to process what had gone on. I hadn't realised what had happened.' Things were then blurry, he said.

Mr Bewick - with knife wounds on his arm, hand, and leg - ran down the stairs, and found Adams in the kitchen, the knife still in her hands.

As he fled, he said, he asked her: 'Why?' Her response was a shrug of her shoulders, he said.

In just his boxers and his socks, he ran the length of the street, and sought help from Adams' aunt, who was outside her house having a cigarette. As he arrived there, he said: 'Zoe's stabbed me.'

She calmly took him in and dressed his wounds, and called an ambulance. Earlier, Mr Bewick spoke about how Adams unblocked on Facebook a man she had fallen out with.

Asked why she did that, he said, she said she wanted to invite him round to kill him.

Mr Bewick then outlined an interest that Adams had in gruesome murder videos.

He said: 'One she showed me [was] of three guys beating up a guy who was unconscious in a wood, with a baseball bat and caving his head in...

'Whereas normal people would be repulsed and where I found myself being repulsed, she was watching it with intent. But she'd be really into it.'

Her comments while doing this were along the lines of: 'How cool is that kinda thing'. She was really into it, he said.

'She would sit, particularly in the mornings when she'd just woken up, she'd just sit on her phone and then scroll through and she'd find these videos and just sit watching them.'

Adams earlier showed an obsession with gruesome murder videos and would frequently watch them on her phone, Mr Bewick alleged

Asked about the human sacrifice message, Mr Bewick said: 'I just kind of passed it off as, like I knew she was, like, just strange; she was just a bit weird.'

He was then questioned by defence barrister Dan Travers.

Mr Bewick confirmed he had written a book called Ascendence, a fantasy novel he agreed was dark and included murders and stabbings.

'I wrote that in what I thought was a way that would make a good film,' he said.

He confirmed having sex with Miss Adams a month or so before he was stabbed, but said after she told him clearly in messages that she did not want it to happen again.

Mr Bewick admitted to being angry at the time but he appreciated it was her decision.

'I didn't want to ruin the friendship,' he said, telling the court that he eventually accepted her decision.

The case continues.
