A man has admitted the “brutal, vicious and cruel” murders of a pregnant mother and three young children.

Damien Bendall, 32, who had previously admitted manslaughter, pleaded guilty to murdering his 35-year-old partner Terri Harris, her 11-year-old daughter Lacey Bennett, her son John Paul Bennett, 13, and Lacey’s friend Connie Gent, also 11, at the home he shared with Ms Harris.

He also admitted raping Lacey at the house in Killamarsh, near Sheffield, in 2021, during what prosecutor Louis Mably KC told the court were “brutal, vicious and cruel attacks on a defenceless woman” and young children.

The Crown’s KC detailed the “truly hideous and dreadful” aspects of the crime, including the fact Ms Harris was murdered while carrying Bendall’s unborn child – a fact revealed by a post-mortem paternity test.

Mr Mably KC, opening the case, said Lacey was likely to have been raped at least twice by Bendall.

Connie had only been due to stay over for one night, but successfully got permission from her mother, fatefully extending her stay by another night – coinciding with Bendall’s attacks, the court heard.

What also emerged was that having brutally killed Ms Harris and the children, Bendall “took John’s Xbox (games console), ordered a taxi, went to Sheffield”, where he then exchanged the console “for drugs”, Mr Malby said.

Bendall would later tell police he had consumed “three to four bags of cocaine and then blacked out”.

“This gives an indication of the sheer callous depravity of the defendant’s conduct that night,” said Mr Mably.

Bendall entered the guilty pleas at Derby Crown Court on Wednesday.

Ms Harris and the children were found dead at her home in Chandos Crescent, Killamarsh, in north-east Derbyshire, near Sheffield, on September 19 last year.

Mr Mably, opening the case, said: “On the night of Saturday September 18 2021, stretching into the early hours of September 19, the defendant brutally and viciously murdered his then partner, Terri Harris, who is aged 35 – and was in the early stages of pregnancy.

“He also murdered Terri’s two children, by a previous partner, her 13-year-old son and 11-year-old daughter Lacey, and he murdered Connie Gent, also aged 11.

“She was a friend of Lacey’s who just happened that evening to be staying at Lacey’s house for a sleepover.”

Nearly all the victims had defensive injuries, indicating they had tried to fight off Bendall after he launched his attack some time after 9.42pm that evening.

Mr Mably told the court: “The circumstances of these offences are truly hideous and dreadful.

“These were brutal, vicious and cruel attacks on a defenceless woman and three young children.

“The defendant attacked them using a claw hammer which he used to hit them over the head and on the upper body.

“It was perfectly clear none of the victims stood a chance.”

Mr Mably said: “It does appear each (victim) was attacked in a different room, (and) appears he went around the house looking for them, attacking them each in turn, in order to kill them.

“One of the dreadful facts about this case is that during the attacks, the defendant raped Lacey, and this included raping her as she lay dying from the head wounds he had inflicted with the hammer.”

Bendall was arrested outside the house shortly after 7.39am on September 19, after his mother had rung 999 telling them he had reported stabbing himself.

Body-worn video showed Bendall, who had two superficial knife wounds, calmly telling police: “I’ve murdered four people.”

Officers asked him: “Do you think you’ve killed your family inside their house?”

Bendall replied: “No. I have (killed them).

“There’s one in the bathroom, two upstairs and one in another bedroom.”

Audio of the police search of the house was then played in court, with a male officer’s voice catching with emotion as he said: “They’re gone, they’re gone.

“They’re all gone.”

After his arrest, Bendall told officers at Ripley police station: “The whole house is covered in claret.

“I used the hammer.

“I didn’t realise what I did until I walked into my room and saw my missus and my daughter.”

He then added: “Bet you don’t usually get four murders in Killamarsh do you – well, five (murders), because my missus was having a baby.”

Mr Mably told Mr Justice Sweeney that a whole life order was necessary in the case because of the “exceptional high level” of seriousness, adding Bendall himself had agreed such an order was appropriate.

Vanessa Marshall KC said her client, who has maintained having no memory of the event, agreed he should be handed a whole life order.

She said: “His actions that night remain largely inexplicable and motiveless.”

She added that he had been “happy” about the forthcoming pregnancy, which would have been Bendall’s first child.

“The defendant hopes the knowledge he will be spending a full whole life sentence behind bars for the rest of his life, where every day he is having to confront the demons of his actions, will provide some justice to these families,” the lawyer said.

The court heard that Bendall, who had previous convictions for robbery, attempted robbery and grievous bodily harm had carried out the rape and murders while on a 24-month suspended sentence handed down at Swindon Crown Court in June 2021 for arson of a car he had tried to steal.

Mr Justice Sweeney said he would consider legal submissions and sentence Bendall later on Wednesday.
