A man who pleaded guilty to brutally murdering his partner has claimed police played a part in the vicious killing.
Stephen Boyd, 53, pleaded guilty in August to the murder of his former partner, childcare worker Tina Kontozis, in her Bundeena home on the outskirts of southern Sydney and to knocking his son unconscious with a bat on April 24, 2016.
During a sentencing hearing in the New South Wales Supreme Court, crown prosecutor Chris Maxwell revealed Boyd had written a letter to his son Daniel and Ms Kontozis in May 20, 2016.
In the letter, Boyd blamed police for his ’emotional breakdown’ which led to the murder of his partner, according to news.com.au.
Daniel Boyd (left, with family and supporters) has told a court that his father – who brutally murdered his mother before beating him with a bat – was an ‘evil narcissist’
‘To this day I still believe the police should not have been called and should not have got involved in our family arguments,’ he wrote.
‘All it did was make things worse because the police overreact and exaggerate the facts and charges, resulting in an AVO [apprehended violence order] then a breach of AVO and a good behaviour bond, all with court appearances, court costs and fines.
‘Police should not have carried on with it, resulting in restrictions and more pressure on me which I believe contributed to my emotional breakdown that terrible day.’
Boyd ended the letter by coming to the realisation that he would be imprisoned for a long time, while also begging for forgiveness.

Earlier in the hearing, Boyd’s son Daniel spoke of the fondness he had for his mother.
‘Rest in peace, mum, I love you and miss you, you will forever be in my heart,’ said Daniel Boyd on Friday at his father’s sentence hearing in the NSW Supreme Court on Friday.
The court heard Boyd repeatedly stabbed Ms Kontozis and hit her with a wooden bat.

In his victim impact statement, the now 19-year-old said his mother’s life was tragically taken away from her in horrific circumstances.
‘I was also assaulted by the offender which resulted in numerous injuries,’ he said.
He now hates going to bed at night, has nightmares and is paranoid about making sure the doors are locked.
‘Mum was just a beautiful person,’ he said, adding that he missed her so much.
‘You may have taken my mother away from me forever but you cannot take my memories.’

Other statements were read out on behalf of Ms Kontozis’s three older brothers and their mother Helen Kontozis, with whom her grandson Daniel now lives.
She described the cruel burden of ‘having to bury my baby girl’ who was murdered by a selfish bully in a barbaric manner.
‘My daughter’s son Daniel is effectively an orphan,’ she said.
Tina’s brother James Kontozis told the court he was haunted after being given his sister’s deformed rings – a sign of the trauma she had suffered before her death.
‘I couldn’t imagine the trauma Tina endured in her final moments …. but when I was given the rings she was wearing and saw the deformed state they were in I came to the realisation that she would have suffered horribly,’ he said.
Brothers Nick and George Kontozis both said they felt guilt for not protecting their little sister.
The hearing continues.
