Pregnant Sarah Bramley has been jailed for inciting an offence by sending a photo of herself performing a sex act on a man, who was then murdered

A pregnant mother-of-two who sent a photo of herself performing a sex act on a man - who was then murdered by her jealous ex - will serve just two months in jail for inciting the attack.

Sarah Bramley, 29, sent a photograph of herself performing oral sex on Michael Lawson to violent David Saunders, with the message: 'Feel free to smack the c***.'

Saunders flew into a rage and stabbed Mr Lawson to death in Darlington as he walked home from Bramley's house after she ordered him to leave.

Saunders was jailed for life last year and Bramley was ordered to serve four months today - meaning she should be released before she has her baby.

Bramley admitted inciting an assault after it was accepted she could not have foreseen her goading of Saunders would lead to Michael's murder.

Bramley will be entitled to automatic parole half way through her four-month jail term.

Mr Lawson's uncle Ray Scaife said after the hearing: 'We're glad she went to jail, it's the only fair sentence, she deserves to be in prison, it's a shame it couldn't be longer.

'She knew she was winding up a violent man and at the very least she knew that Mike was going to get a good hiding.'

Explaining the charging decision in court, prosecutor Nick Dry said: 'It was never the Crown's case that Bramley had intended or encouraged that tragic outcome, rather that messages had contributed to the chain of events which ultimately led him to do as he did.'

It was the culmination of a 'love rivalry' with Bramley in the middle, the court heard.

Mr Dry said: 'She was involved in an on-off relationship with both men over a period of months.'

She continued to see Saunders despite her gaining a non-molestation order against him, and knowing he was capable of violence.

Mr Dry said: 'Their text messages revealed a love-hate relationship involving sexually explicit messages of love mixed with highly offensive personal abuse.

'At the same time she continued to see Michael Lawson, a kind, mild-mannered man with whom she had previously holidayed abroad.

'Bramley declared her love to Saunders and then revealed she had recently slept with Mr Lawson. She appeared to revel in the drama and attention of the situation.'

Both Bramley and Saunders were drinking as they exchanged unpleasant texts that night and into the early hours, and Saunders threatened to go round to attack Mr Lawson.

The argument continued and he sent a female friend of Bramley - who was with her at the time - a video of him and his ex having sex.

Bramley responded by sending him a photo of her performing oral sex on Mr Lawson taken that night, causing Saunders to become enraged and he got a taxi close to her home.

He arrived a short time after Bramley had got Mr Lawson out of her house and he was stabbed following a short chase.

Bramley had sent a text at around 3.30am telling Saunders his rival was outside and 'feel free to smack the c***'.

She was later to tell the police she turfed Mr Lawson out because she feared what would happen if Saunders came to her house.

Within days she left to go to Australia and was arrested on her return to the UK in March.

Robert Newcombe, defending, said: 'Miss Bramley had lost her moral compass at the time she was affected by substance abuse and alcoholism.'

He made an apology on her behalf to the court and to Mr Lawson's family, who sat in the public gallery.

Judge Stephen Ashurst said: 'Although you did not contemplate that Saunders would go on to kill Michael Lawson, I take the view it is hard to conceive a more serious case of encouraging the commission of a commons assault.'

He noted that the sexual contact between Bramley and Mr Lawson and the messages she sent Saunders that night were done when her two young sons were in the property.

Bramley did not visibly react as she left the dock.

Speaking after Bramley pleaded guilty, Michael Lawson's mother Anne Satterthwaite, 61, said: 'As far as I am concerned she has got away with murder because without her my son would still be here.

'I hate the lad who put that knife into my son but I hate her more because she caused it to happen.

'She's a narcissist who liked the idea of two men fighting over her, it's twisted but she's going to get away with it.

'She knew what she was doing, she knew that man was violent and had at least some idea he might have a knife.

'Michael had no idea what was about to happen to him when he left her house, he was like a lamb to the slaughter.'
