Mr Baker was sentenced to 15 years in jail today for raping the woman, who cannot be named, before allowing friends to do the same while he filmed them.Caroline Baker had been jailed for three years - but she will only serve 18 months in prison with the remainder on licence.The whistleblower, known in court as Miss X, was assessed as suffering chronic post-traumatic stress and said she suffered 20 years of abuse after starting a second family with Baker.But prosecutors decided there was not enough evidence to prosecute Keith Baker for those allegations.Keith and Caroline pleaded guilty to a string of horrific sex offences against the single woman who had been living at the property for nearly a decade.
Throughout police questioning Baker denied the allegations and claimed all the sex was consensual.
Witnesses told police there was always strange men coming and going from the house and after they seized tapes of unidentified men being filmed having sex with the victim, detectives suspected Baker was pimping her out on the internet.
He locked his mentally disabled victim away for years in a tiny room - not allowing her to leave or even see a dentist or doctor.
The abuse was at their specially adapted home, which consisted of two terrace houses knocked through to make one large home.
Baker's wife Caroline was working as a care worker at a home in Northern Ireland that specialises in mental health residents right up until she was arrested.
Eight years after she was taken to Northern Ireland by her captors, police rescued her from the house in Craigavon, County Armagh, in 2012.
