A MAN has been jailed for 10 years for the regular and systematic abuse of his stepdaughter over a four-year period.
The now 23-year-old victim, who last week described William Coster as “a horrible monster” who took her childhood, has said that she is happy for him to be named in the media.
Coster (44), of Boghall Cottages, Boghall Road, Bray, pleaded guilty at the Central Criminal Court to a number of sample counts of sexually assaulting her, but had pleaded not guilty to additional charges of sex assault offences as well as 13 charges of rape and 22 charges of anal rape.
The victim was aged between 12 and 16 years old.
He has been in custody since he admitted those offences early last year.
Last December, the jury acquitted him on all the anal rape and rape charges but convicted him on every sexual assault count following a three-day trial.
Sean Gillane, prosecuting, said that there were now a total of 49 charges of sexual assault before the court dating between 2002 and 2006.
The court heard that Coster admitted to his wife when confronted, that he had both kissed and touched her daughter.
He immediately left the family home, but sent more than 2,000 text messages to his victim and her mother, again admitting his guilt and saying he deserved what was coming.
Mr Gillane said the victim was brought up to believe the man was her biological father. He first molested her following a family holiday in 2002 and continued his abuse when they returned home.
Mr Justice Paul Carney declared Coster a sex offender and said he was taking into account the inherent gravity of the offence, the breach of trust involved, the age of the victim and the disparity in age between her and Coster, as well as the multiplicity of offences and the effect on her.
He took into account Coster’s admissions, remorse and the fact that he left the family home when required to do so.
Mr Justice Carney sentenced Coster to 10 years in prison for those charges he was convicted on by the jury and a concurrent eight year term for those he pleaded to.
He imposed 18 months post-release supervision.
Mr Gillane said the abuse was also accompanied by “an air of menace and control” as Coster was a controlling person who threatened his step-daughter if she told anyone what was happening.
