The family of a man who reportedly murdered a 22-year-old woman in an act of cannibalism say they are in "complete shock".
Cerys Marie Yemm died from her injuries at Sirhowy Arms Hotel, a homeless hostel in Argoed, Blackwood, South Wales on Thursday.
Her attacker, 34-year-old Matthew Williams, who had recently been released from prison, also died at the scene shortly after police discharged a 50,000 volt Taser and arrested him.
His family told the BBC they were "devastated by the death of an innocent young lady".
"Our thoughts and prayers at this time are with the victim, her family and friends.
"Words cannot express our grief."
Gwent Police said that while under arrest Williams became unresponsive and officers and paramedics administered first aid but he was pronounced dead.
Officers are treating Miss Yemm's death as murder and are not looking for anyone else. Her family, and officers who attended the incident, are being supported by specialist officers.
Police have refused to comment on the specifics of the incident, but sources confirmed the victim suffered substantial facial injuries.
Miss Yemm, who worked in sales at Next, was described as a fun-loving young woman who had been at a Halloween party with friends just days before the attack.
It is believed she met her attacker through mutual friends.
Friends of Miss Yemm as well as locals expressed their shock at the news.
Gareth Griffiths, who lives in Argoed, said: "We heard on the news that it has been cannibalism. Nobody wants to hear that, it must be a horrific way to die, it's horrible, it's unbearable."
A friend of Miss Yemm, who did not want to be named, said: "I feel stunned, shocked and sick to my stomach. It's horrific. She was a lovely person. She didn't deserve to die like that."
Scores of tributes have been paid to Miss Yemm - whose family and friends have been left devastated by her death.
