Leanna Mould (pictured outside Newcastle Crown Court last week) had a furious falling out with her partner Michael Stead
A mother has been found guilty of plotting to have the father of her child beaten up shortly before her brother murdered him.
Leanne Mould, 34, had a furious falling out with her long-term partner Michael Stead, also 34, after she accused him of cheating and claimed he had taken £30 belonging to her.
Jurors were told Mould conspired with her brother Daniel Mould, 26, and Trevor Creighton, 33, all from Sunderland, to commit grievous bodily harm on Mr Stead.
Newcastle Crown Court heard on March 21 there was a row involving the siblings and Mr Stead and Daniel Mould left his sister's home - before returning less than two hours later and launching a vicious attack on the victim with a hammer and steel sharpener.
Mr Stead suffered serious head injuries in the street near his home and died nine months later.
Daniel Mould has now been convicted of his murder while he and his sister were found guilty of conspiracy to inflict GBH, along with Creighton.
A third man, Michael Young, admitted manslaughter after jurors failed to reach a verdict on the murder charge.
Prosecutor David Brooke QC told the court Leanne had accused Mr Stead of 'unfaithfulness' and said that he had 'stolen from her'.
This led to an angry confrontation outside his home at around 9pm on March 21.

Mr Brooke told the court around an hour-and-a-half later, the four went to the house and there was a second stand-off.
The Newcastle Chronicle reports that the court heard there had been an angry confrontation around 9pm on March 21, involving the Moulds and Creighton.
That was then followed by a serious assault around 90 minutes later.
Mr Brooke told jurors: 'Leanne Mould, with her brother Daniel Mould and Trevor Creighton are charged with conspiracy to commit grievous bodily harm upon Michael Stead in relation to what led up to his death that night.'
The court heard all four were at the scene at some point during the second, fatal, confrontation but only two defendants are accused of the murder.
Mr Brooke added: 'There was a confrontation at about 10.30pm with Michael Stead outside his home.

'That involved Daniel Mould, Trevor Creighton and, at that time, Michael Young as well, at a time when Leanne Mould was also present.
'The prosecution say the three male defendants left after an initial incident, where there was some form of confrontation.
'Then, Daniel Mould and Michael Young, the first two defendants, came back to the scene and it was then they inflicted injuries on Michael Stead, in an attack that ultimately led to his death.'
The court heard a witness who saw the aftermath of the attack saw Mr Stead 'lying motionless in the road' with his head 'covered in blood'.

Another witness told police she saw Young walking away from the scene, saying 'we've killed him, we've killed him'.
Mr Stead was taken to the Royal Victoria Infirmary in Newcastle after the attack with extensive head fractures and bleeding around and within the brain.
He had surgery to relieve pressure in the brain but remained in a persistent vegetative state until he died in hospital.
Daniel Mould, 26, Young, 26, Leanne Mould, 34 and Creighton, 33, will be sentenced on Friday.
