Ronnie Phillip Charles Lovett, 22, was instead convicted of the manslaughter of George Asprogiannis [also known as Trindall ], 27, who died after being stabbed through the heart on August 10, 2008.

Angry and disappointed, Mr Asprogiannis senior said he was at a loss to understand the jury's decision and described Lovett's version of what happened on the night as a load of "bulls***".

He also described the anguish of losing his son, saying "I've got nothing left now".

"George was right handed, there's no way he grabbed the knife with his left hand [as Lovett suggested in evidence]," Mr Asprogiannis told the Weekend Advocate.

"And there is no way George fell on that knife.

"You don't fall on a knife in that direction and have it go straight through you."

Mr Asprogiannis senior said if his son had held the knife, as Lovett said in evidence, he would expect defensive cuts to be on Lovett's hands and body.

"I've been in the same situation myself, in a fight with someone armed with a knife and I had defensive cuts all over me," he said.

"He [Lovett] didn't have one mark.

"And someone had to put that knife there ... Is he trying to say George went to their house and got it?"

Mr Asprogiannis said he sat in for most of the three-week trial but decided he couldn't stay in the court any longer after hearing Lovett's evidence.

"It was too much. I couldn't take any more of his bulls***," he said.

Ms Asprogiannis senior said it was very hard to have to sit and listen to how Lovett continued to assault his son after he'd been stabbed.

"Why did he have to kick the s*** out of him? Why did he have to do that? He was already dead on the ground," he said.

Despite the finding, Mr Asprogiannis senior said he felt sympathy for Lovett's family.

"I feel very sorry for his family, but I've lost my son. I'm crushed. I just can't take it any more," he said.

"These last three years, it's the longest time I've been out of jail in my entire life, but after this I just think I'm better off going back in. I've got nothing left now."

Discharging the jury yesterday, Justice Barr thanked them for the valuable contribution they and every jury make to the community.

Lovett will be sentenced in Sydney on Wednesday, December 16.

No bail application was made by Lovett and Justice Barr formally refused bail, remanding him in custody until December 16 for sentencing.
