William Parker, the brother of slain man Kenneth Wayne Parker, read his victim impact statement to the Supreme Court of NSW sitting in Griffith during sentencing submissions on Thursday.

Kenneth Wayne Parker was stabbed in the back by his wife Marianne Parker in their Monash Street home in West Wyalong between 6.30pm and 7pm on December 16, 2013.

On April 15 a jury found Parker not guilty of murder but guilty of the lesser charge of manslaughter of her husband.

Mr Parker said he felt robbed over the loss of his brother.

“Ken was not just my brother, he was my mate,” he said.

“Growing up myself and Ken were very close.

“I felt an enormous loss as Kenny had such a tormented life.”

Mr Parker said if there was such a thing as heaven, he knew his brother was now there because he went through hell while on this earth.

The court heard that the victim had led a tormented life after accidentally discharging a gun and killing his father when he was only 13.

“After this Ken changed,” Mr Parker told the court, describing how his brother became a heavy drinker.

“I once asked him why he drank so much, to which he replied ‘it helps me to forget’.”

Mr Parker said he believed that if his brother had counselling it might have helped him to move forward into the future, however, without it he blamed himself despite being told what happened wasn’t his fault by family.

“He never did forget or forgive himself,” he said.

Mr Parker said his brother had difficulty at school because the other kids constantly tormented him over what had happened.

Following school, his brother’s life continued to bring him no peace. He returned home after work one day to find his wife Pam and stepson had left him, leaving him nothing but his hat and boots.

He then met a lady named Roslyn who would eventually stab him in the chest with a steak knife, he spent two weeks in hospital as a result.

Mr Parker said he spoke with his brother on the phone while he was in hospital and asked him if he would press charges, to which he replied ‘no she loves me’.

Mr Parker told the court he visited his brother in Condobolin while he was in a relationship with Marianne Parker.

He said that his brother had come out to see him and his children in the car and that Marianne Parker had come out of the house intoxicated and hurling abuse.

He said after she spat on the window of the car he and his family left.

Mr Parker described to the court the moment he found out that his brother had been killed and said words could not describe the pain he felt.

“We were at home, wrapping Christmas presents,” he said.

“Christmas time is no longer the festive season as it’s a sad reminder of the loss of my brother.”

Mr Parker appealed to the court to find justice for his brother, saying he was unable to find justice while alive.

“I feel he is worthy of justice,” he said.

“I regret that Kenny never found happiness and that he never forgave himself.”

Mr Parker said he knows his brother has seen his father in heaven and told him that he forgives him.

Marianne Parker sat quietly in tears in the dock as Mr Parker read out his victim impact statement.

Justice Rothman reserved sentencing and adjourned the matter of sentencing to May 25, 2016.
