On a night out in Blackwood in October 2014, Cerys Yemm, met Matthew Williams, 34.

Cerys, 22, was a retail worker who lived with her mum.

Over the next fortnight, the two stayed in touch over text, and on 5 November they met up again.

That night, Cery’s failed to return to the home she shared with her mother as planned.

Instead, she went with Williams to the Sirhowy Arms Hotel in Argoed, Blackwood, where he had a room.

They arrived about midnight.

By 1am screams were heard coming from Williams’ room.

The hotel’s concerned owner opened to the door to a scene of sheer horror.

Williams was on top of Cerys, who showed no signs of life.

There was blood pooling around her.

It was believed that Williams was eating her face.

Williams was aggressive towards the owner and continued to attack Cerys.

So she called the police who arrived and restrained Williams using a Taser.

It killed him and he was declared dead at 2.18am, despite attempts to resuscitate him.

His victim Cerys was already dead,with  devastating injuries to her head and neck.

Later it emerged that Williams had a long history of psychiatric problems.

He had a total of 26 convictions against 78 offences and had been released from prison just two weeks before he killed Cerys.

The Sirhowy Arms was a halfway house and Williams had been provided a room there by Caerphilly County Borough Council.

It’s unclear if Cerys knew any of this when she returned to the hotel with Williams.

A post mortem recorded a provisional cause of death for Cerys as sharp force trauma to the face and neck.

In March 2017 an inquest into the deaths of Cerys Yemm and Matthew Williams began.

The allegations of cannibalism are yet to be proved and weren’t mentioned to the jury at at Gwent Coroner’s Court.

The inquest is expected to last three to four weeks.
