child sex offences and was jailed for over three years

Rachel Marshall, 42, was jailed for 40 months after admitting child sex offences

A 'model mother' who had weekly sex sessions with a schoolboy in her car has been jailed.

Rachel Marshall, 42, plead guilty to four counts of sexual activity - including sex - with a child and was jailed for 40 months at Caernarfon Crown Court in Wales.

She had also admitted two charges of meeting the boy following sexual grooming.

The trial heard how she met up with the 15-year-old for sex in her house and when he began to see a girl his own age she sent abusive texts saying 'You are both f***ing dead'.

To intimidate him further she pretended to be pregnant and sent him a fake scan and the girl, a pregnancy magazine.

Prosecutor Simon Rogers said Marshall, from Llandudno Junction in Wales, had started sending 'flirtatious' messages to the boy and eventually asked if he would like to go for a drive.

She picked him up near his home and they went to a car park on the picturesque Sychnant Pass, above Conwy, Wales, where Marshall spoke about difficulties in her marriage.

The defendant then kissed the youngster and her behaviour escalated. The pair had sex almost weekly including at Marshall's home. But the romps were normally in her car.

When he began to lose interest she became obsessed with him, showering him with gifts including aftershave, a new iPhone and cash.

Prosecutor Simon Rogers said: 'Her [Marshall] behaviour began to freak him out. She wouldn't leave him alone. She was continually messaging him. The defendant wouldn't let him stop what was going on.

'She would send naked photographs of herself to him and began contacting his friends.'

The mother also bombarded him with text messages during a campaign that he called 'relentless'.

When the teen refused to contact her she created fake social media profiles and continued to send abusive messages.

She also posted notes through his door, in one saying 'I will wait all day.'

After getting the girlfriend's number Marshall called her repeatedly and sent numerous messages.

Mr Rogers remarked :'This was a deeply unpleasant course of harassment against the complainant and his girlfriend. That was done to manipulate him to continue the relationship with her.'

The judge said: 'He did manage to shake off your attention and started a relationship with another young lady. Clearly you were annoyed and jealous and started sending him unpleasant texts and threatened to expose what he had done with you.

'You went beyond that, contacting the young lady and blackening his character and spoke to her parents.'

Judge Heywood said Marshall was of previous good character and a mother and wife who had a succession of good jobs. There was a psychiatric report and a professor indicated a possibility for her behaviour was the medication she took.

The judge said: 'You clearly were fixated with him [the boy].'

Marshall will be on the sex offenders' register for life and a sexual harm prevention order has been put in place to protect her victim.

Sentencing Marshall, Judge Heywood said the relationship had a 'disastrous' effect on the boy, who had threatened suicide.

He told Marshall :'You knew this young man's age and took advantage of the situation for your own desires.'

Her barrister Sion at Mihangel described her as a 'model mother' and said: 'She is deeply sorry for what has taken place.'

He added: 'She is pregnant, since she's been arrested she has been on a path of self-destruction.

'The child will be born within the prison environment. For up to 18 months it can stay with her. It will be cared for and loved for by others.'
