A Victorian man who gunned down his uncle and father says he prays for forgiveness every night, but cannot remember the murders.
Bendigo man Ross James Streeter initially denied he committed the double murder but decided to plead guilty "out of respect" for his father, whom he loved, the Victorian Supreme Court heard.
The 31-year-old entered the plea in September but has never provided details of what happened on March 14, when he shot dead his father Doug and uncle John Streeter, both in their 60s, at their sheep farm in Natte Yallock.
His lawyer Michael O'Connell SC told the court on Monday he unequivocally accepted responsibility for the deaths but doesn't remember committing them.
In letters to his mother from prison, Streeter said it upset him to think he could do such things.
"I am scared and don't know what's going on," he wrote.
"I'm sorry to you especially, beyond words, I am so, so sorry."
Two days after the murders, Streeter was found at a water tank near the rural Victorian property with deep lacerations to his wrist.
He was discovered after he sent a text message to his brother saying he had "gone to be with Dad and Jack" and asking that his brother look after their mother.
In victim impact statements read to the court, family members wrote of their difficulty in comprehending what happened.
Mr O'Connell said there was not the slightest suggestion of any animosity between Streeter and his father and uncle.
A week before their deaths, the elder Streeters had rewritten their wills to bequeath Ross a one third share in the sheep farm.
Doug Streeter, who was dying of motor neurone disease, had kept a diary of his last few weeks, which included an entry about Ross Streeter fixing a problem with the internet at the house.
He wrote "Ross to the rescue again" on February 21, less than a month before he was shot by his son.
Crown prosecutor Mark Rochford urged Judge Lex Lasry to hand down a substantial jail term.
"Mr Streeter, because he has no apparent insight into his behaviour, remains a danger to the community when he is ultimately released," Mr Rochford said.
In letters to his mother, Streeter wrote that he was ready to accept his sentence.
"No matter how long it is it will never replace my father," he wrote.
"I pray for forgiveness from him every night."
Streeter will be sentenced on December 18.
