The emotionally charged sentencing of 29-year-old Jolly who snatched a six-year-old girl from the street outside her Wagga home and repeatedly sexually assaulted her at two locations had to be suspended twice for his mother Glenda to compose herself after breaking down while answering questions from her son's barrister John Weir and then Crown prosecutor Max Pincott.

Mr Weir asked Mrs Jolly if her son had told her how he felt about his offences.

"He is absolutely disgusted about what he has done, he does not know how to live with himself (as a result of) what he has done, his chest aches all the time," Mrs Jolly answered as her son's sobs filled the courtroom.

Judge Jennifer English called a temporary halt to proceedings as mother and son sobbed and the little girl's mum fled the court.

After the resumption, Mr Pincott read out graphic details of each of Jolly's repeated assaults on the girl and asked Mrs Jolly if she was aware of them.

"When you read all these allegations (in agreed facts), what was your reaction?" Mr Pincott asked.

“I could not believe it was my son,” she replied.

After Mr Pincott read out more of the allegations, Mrs Jolly broke down a second time and gasped: “A mother should not be expected to do this.”

Judge English will sentence Jolly on Monday.

Jolly, of Albury, has pleaded guilty to two counts of indecent assault of a person under 16 and one count each of sexual intercourse with a person under 10, assault with intent to have sexual intercourse with a person under 10 and take and detain a person with intent to obtain an advantage.

In his sentencing submission, Mr Pincott spoke of how Wagga was gripped by fear as news spread of the kidnapping on Valentine’s Day two years ago.

“The whole community held its collective breath while they awaited the fate of this child,” Mr Pincott said to Judge English, who said she was also in Wagga at that time.

He asked the judge to imagine the horror as the child’s mother attempted to grab the back of Jolly’s utility as he drove off with the girl and how she was left clutching the air and trying to get the vehicle’s registration number.

“One would think it was out of a Hollywood script,” Mr Pincott said.

In a letter submitted to the court, Mrs Jolly spoke of her family’s fears of reprisals for her son’s crimes.

“Did you consider the fear that (name of little girl’s mother) felt?” Mr Pincott asked.

“Yes I know her fear,” Mrs Jolly said, revealing to the court an experience of sexual assault in her own family and how she once lost one of her own children for 30 minutes.

“If I could take it away from her I would, if I could take her burden I would, if I could change everything I would, but I can’t,” Mrs Jolly said, who earlier blamed herself for her son’s psychological problems because she was too preoccupied by family financial problems and another son’s epilepsy to do anything about them.

“That is my regret, I should have done more for him, I should have been more intuitive for him and his feelings, I never had time for Adam,” Mrs Jolly said.

In her evidence, Mrs Jolly described her son as a loner who never adapted to living in an urban environment in 2007 after being on a farm for most of his life.

“He was lost in a world he didn’t know,” Mrs Jolly said.

“I feel his family life was not normal by any stretch of the imagination.”

She said her son had been assaulted in jail, had urine squirted into his cell and had received death threats.

Mr Weir said psychologist Dr Bruce Westmore had given an explanation for Jolly’s offences: disturbed psychology.
