Two young boys present when their dad was shot dead by a Victorian chilli farmer have spoken of their pain since the death of their "beloved" father.
Angelo Russo, 55, last week pleaded guilty to the manslaughter of David Calandro, who was shot while sitting in his ute at Russo's Tatura farm on February 18, 2017.
The plea came days after his murder trial began in the Supreme Court of Victoria, with Russo admitting to manslaughter after prosecutors agreed to withdraw the murder charge.
Following Russo's guilty plea, the prosecution conceded it could not prove the farmer intended to shoot Mr Calandro.
During a pre-sentence hearing on Wednesday, prosecutor Nicholas Papas QC said Russo claimed Mr Calandro deliberately swerved at his dog Harry to "spook" it, but accidentally ran it over.
Russo claims he was "pissed off" and put down his injured dog by shooting it.
He says he did not intentionally kill Mr Calandro when he approached him with the shotgun still in his hand.
The farmer claims he slipped on an eggplant and the shotgun discharged accidentally and didn't realise Mr Calandro was injured until he heard the 43-year-old screaming.
Mr Calandro died in hospital the next day.
In a police interview, Russo said: "he's put me in a f***ing situation, the f***ing a***hole" and that Mr Calandro was a "f***ing c***".
However, his defence barrister Patrick Tehan QC told the court on Wednesday that Russo expressed "the deepest of sorrow" for his victim's sons and "was tearful and beside himself about what happened".
Mr Tehan also said Mr Calandro and Russo had been friends - a claim that prompted several family members to storm from the court.
Mr Calandro's son Anton gave an emotional victim impact statement to the court, read by a family member.
"My life is different since my dad hasn't been here," he said in his statement.
"My dad was a nice, caring, fun dad.
"I now have to do more things at home because he's not here. I have to care for mum."
A statement by Mr Calandro's other son, Flavian, was read to the court by Mr Papas.
"My beloved dad was killed in front of me and my brother," he said.
"It is too hard, I feel pain in my body.
"My dad was a fun-loving guy and he'd do anything to make me and my brother happy.
"I will forever miss my dad knowing he is gone from this earth."
The court was also told Russo's mother died while he was in custody over Mr Calandro's death, having burnt to death when her dress caught fire.
The hearing continues on Thursday.
