UPDATE: A split-second decision ended the life of a man being hailed a hero.
Norman Olsen could have turned a blind eye to the young woman, a baby in her arms, cowering on the footpath of a busy Toowoomba street Monday afternoon.
Mr Olsen, 65, could have been like any other motorist driving that stretch of road around 3pm but he wasn't.
The Vietnam veteran, who served with the 110th Signal Squadron in South Vietnam from 1971-1972, stepped in and paid with his life, the victim of an alleged brutal shove to his chest that propelled him backwards and struck his head with such force he suffered bleeding on the brain.
Toowoomba detectives have secured the sickening footage of the alleged assault which they believe "paints a full picture of what actually occurred at the time".
"(Mr Olsen's) acts obviously were done because he saw person in distress and he put himself in harm's way," Darling Downs Detective Acting Inspector Paul McCusker said.
"He has paid the ultimate price for that and all I can say is that is a very courageous act that he has done."
Mr Olsen and his wife Isobell had been in Toowoomba four days visiting friends when he intervened in the disturbance.
His family switched off the life support that had kept him a viable organ donor in the early hours of this morning.
Det. Insp. McCusker said passers-by first came to Mr Olsen's aid when he lay unconscious on Bridge St, just metres past the Druce St intersection in Wilsonton, after he fell to the roadway.
While commending his actions, Det. Insp. McCusker said police should always remain the first "port of call" in violent situations.
"In this instance he's come forward to help a person in distress and I think he must be commended for that," he said.
"There were a lot of people who actually stopped their cars and got out and since that time, people have come forward with that they saw.
"The CCTV footage we have obtained gives us a true and accurate picture of what has occurred.
"Any assault of that nature, where someone is seriously injured, is sickening to see and obviously a very distressing event."
Mr Olsen leaves behind an extended family which is being supported by authorities.
His wife and daughters rallied by his hospital bed in Brisbane, and an online fundraiser has gained support from across the country as people react to the tragedy.
Det. Insp. McCusker said Mr Olsen's actions Monday afternoon had been almost instinctive when he tried to save a woman and her baby from being bashed.
"People will help each other, it's in our nature to help each other," he said.
"I think in this instance it has come up with a very tragic result.
"I don't think you can make comment as to whether people will help each other at the time (but) quite obviously here, Mr Olsen decided to help the person on the ground which is very courageous and he's paid the ultimate price for that."
11.30AM: The Queensland Premier has offered her condolences to Norman Olsen's family in the wake of his death this morning.
Premier Annastacia Palaszczuk said Mr Olsen's actions ended with "tragic consequences" after he stopped to help a woman in distress in Wilsonton Monday afternoon.
"(He was) stopping on the side of the road to provide assistance to a woman in distress with tragic consequences," the AAP quotes Ms Palaszczuk as saying.
"So my thoughts and prayers are with the family."
9.15AM: James Darren Callow, 22, did not appear in court this morning and remained in the Toowoomba watch house.
His solicitor, Sarah Gordon, told the Toowoomba Magistrates Court there would be no application for bail and she did not require for her client to be brought to court.
Ms Gordon asked for an adjournment so a police brief of evidence could be produced.
Magistrate Graham Lee therefore remanded Callow in custody and adjourned the case for committal mention back in the same court on April 27.

Norman Olsen, a Vietnam veteran, father and grandfather, has been hailed a hero for stepping in to try and stop the assault.
He died early this morning.
"Putting your life in harm's way defending another," one man wrote on social media.
"It was not your fight but you did the right thing.
"A true hero. I honour your bravery."
A gofundme account set up in Mr Olsen's name to help cover funeral costs has received support from around the country as people wake to the tragic news today.
"Norman was a father and husband who without thinking about his own wellbeing stepped in to help a complete stranger and ended up paying with his life," the page reads.
"He is a true hero who did not deserve to this (sic)."

6.16AM: Norman Olsen was as selfless in death as he was when he intervened to save a woman being bashed on a busy Toowoomba street.
In the small hours of this morning, the 65-year-old's life support was turned off, his organs donated to help save yet more lives.
Mr Olsen, from Tweed Heads, had been driving along Bridge St just past the Druce St intersection when he spied a woman allegedly being assaulted on the footpath.
He pulled over to help - a decision which would ultimately leave him brain dead after he was allegedly pushed into the ground by a 22-year-old assailant.
He was taken to Toowoomba Hospital before he was airlifted to Brisbane where his family rallied by his side.
Mr Olsen was never to wake up and at 2am today, his organs helped save lives.
He had been kept on life support overnight to enable his organs to be donated today, a decision his family says reflected the generosity and spirit of Mr Olsen.
A man is due before Toowoomba Magistrates Court today on charges arising from the alleged Monday afternoon incident.
