Twisted tale of how a young woman, 29 and her much older boyfriend, 52, befriended sisters, aged 8 and 4, to sexually abuse them - as itnis revealed they even filmed the vile acts

A woman and her 54-year-old boyfriend are accused of befriending and sexually assaulting two sisters after meeting them on holidays.

Laken Maree Rose, 31, and Andrew Alan Williams started filming the eight and four-year-old girls being raped after meeting them at the Bay of Plenty camping ground, southeast of Auckland, in late 2018.

After the oldest child told her mother about a series of disturbing sexual 'games' the couple 'played' with her, police found images and videos of five more children being abused by the couple between 2014 and 2019.

Altogether, police found more than 150,000 sickening photos and videos of child abuse in their home.

Williams pleaded guilty to 56 charges of abusing seven victims between three and 14, and faces decades in jail.

Rose pleaded guilty to nine charges of inducing an indecent act on a young person, and making a film showing the sexual exploitation of a young girl knowing the video was objectionable.

But Rose denied other more serious allegations and pleaded not guilty to 50 charges of child abuse in Hamilton's High Court on Monday, and her case will be decided by a judge alone.

After experts interviewed the sisters in May 2019, police searched the couple's home in Cambridge, south of Auckland, and found children's underwear and sex toys.

Williams and Rose strongly denied the girls' allegations when interviewed by police, with Williams asking: 'Who would believe a nine-year-old over me?'

Despite their denials, the couple were arrested and charged with sexual violation and indecent assault. Williams was detained while Rose was allowed out on bail. 

Two days later, Rose called Detective Bryan Dudley to say she found her partner's second phone.

Four days later, she rang again to say she found Williams' laptop which contained thousands of images of young children downloaded from the internet.

When analysed, police uncovered an additional 450 hours of footage and photos of Williams performing sex acts on young girls. 

Rose, who used to be a jockey, claimed  Williams scared her into grooming young girls for him

The videos were used to identify four of the five additional victims between the ages of three and 14. The seventh victim has never been identified.

When confronted by police about a video that showed Rose having sex with a 14-year-old, she replied: 'I don't really remember that year, at all'.   

The former jockey claimed Williams, who she met at the age of 19, was controlling and threatened to kill her if she did not comply with his depraved wishes.

'He strangled me, he beat me, he made me feel worthless. He took me away from everyone, no one would ever help me or love me,' Rose told Dudley.

When she found Williams in the bath with a young girl they were supposed to be caring for, Rose said her boyfriend put her 'head through a wall' because she refused to film it. 

She claimed Williams would dress her up as a schoolgirl in pigtails and force her to perform sexual acts she was not comfortable with.

Rose said the first time Williams strangled her, he grabbed her by the neck and yelled: 'Why do you have to make me so angry, why can't you keep me happy?'  

She explained that she was so scared of her partner that she agreed to hold up a phone or a laptop so he could see images of young girls while they had sex.

Eventually, the woman said her fear was a driving force when she agreed to source children for him to photograph.

When he went further and sexually abused them, Rose said she was too frightened to stop him. 

She said that she thought Williams wanted to photograph the girls, and was too scared to intervene when he started assaulting them

Rose also claimed she found footage of Williams on his phone abusing the three-year-old daughter of a friend.

'He told me if I told anyone I wouldn't survive the week,' she said.

Thousands of text message conversations between Rose and Williams were also uncovered, each of which discussed victims in extensive detail.

When asked about them, she explained that she was trying to keep him happy. 

Rose pleaded guilty to 10 charges relating to a single victim - one of inducing her to perform sexual acts, and one of making a video.

The maximum sentence for filming an offence is 14 years in prison 

Justice Matthew Muir hopes to release his ruling by Christmas. 

Williams faces 20 years behind bars and will be sentenced in February.
