Two admitted to hospital in shock after witnessing Bourke Street incident

An emergency doctor working at St Vincent's Hospital today said two patients were so shocked by what they had seen, they needed medical care.

Dr Neil Cunningham, the senior doctor who coordinated St Vincent's response to the event, said one "extremely distressed" person who had not been hit by the car was brought in by ambulance with chest pains and may be suffering from a heart attack.

Another person was "very much in psychological shock" after witnessing the crime and had been admitted for treatment.

"It's not unheard of that people sustain heart attacks from stress," he said.

Dr Cunningham said St Vincent's received another five patients with multiple injuries. All were clearly in pain and conscious when they arrived. Some had blood on them.

About 60 staff were rallied in the emergency department to care for the patients who are all stable tonight. Dr Cunningham said the health system appeared to work well today, and that staff would have to debrief to look after their own health and to learn from the experience.

"I feel incredibly proud of all the staff at St Vincent's today. We had an environment that was respectful and understanding of the fact that the people coming through the door had been through a very, very distressing event," he said.

Bourke Street Mall driver identified as James "Jimmy" Gargasoulas

The man who allegedly mowed down 18 people in Melbourne's CBD on Friday, killing three and injuring 15 others, has a history of drug use, violence and psychological problems.

James "Jimmy" Gargasoulas, 26, lived in public housing flats in Windsor, where he allegedly stabbed his brother, Angelo, in the early hours of Friday morning.

A relative said Jimmy has had a drug problem and has been in and out of jail for car theft and drug offences.

"Jimmy has always been a bad person," she said. "I knew it was him. I saw it on TV ... the picture of him sticking his head out when he was doing burnouts.

"I saw a picture and I thought 'Oh My God, that's Jimmy.' I'm shaking. I knew it, as soon as I saw that picture I had this feeling. I can't believe this.

"I balled out crying when they announced that baby died. I'm shaking, I just can't believe this."

Comment from The Age's top writers

John Silvester

Crime reporter John Silvester writes that the arrested man was deliberately running down pedestrians on Bourke Street. "The extent of damage to the offender's vehicle shows that he hit his victims at speed, with one being dragged under the car and others smashing on the bonnet and onto the roof."

He writes today's events show how susceptible any peaceful city is to random attack and simply cannot be defended.

"The attack on pedestrians by a known violent, charged offender with a history of drugs abuse and mental health problems will lead to calls for the bail structure to be scrutinised in the same way," he writes.

"There will be outrage and calls for major reforms. And this time the law makers will be forced to listen."

Killer driver highlighted how susceptible city is to attack

Daniel Flitton

The Age senior correspondent Daniel Flitton writes the city has been terrorised, although not by an act of terrorism. 

"This might not be an act of politically motivated violence, but the shock and trauma should not be discounted just because it doesn't fit into some grand narrative of global mayhem," he writes. "It is not September 11, 2001, but nonetheless, the dead and injured are someone's sons and daughters."

The press conference on the Bourke Street incident

Premier Daniel Andrews and police commissioner Graham Ashton spoke to media about the incident about 5pm. 

Chief Police Commissioner Graham Ashton said a man and woman in their 30s and a child died in the incident.

The adults and child are not believed to be related, and were hit at separate intersections on Bourke Street, he said.

Fifteen people were injured by he vehicle, including five who are critical.

An infant child in a pram who was hit by the car was treated at the scene by emergency services and was driven in a police car to hospital where it is in critical condition. 

Mr Ashton believes the death toll "could in fact rise".

Police believe the 26-year-old offender had mental health issues, and has came to police's attention due drug-related issues and family violence assaults, leading to police charges last weekend. 

Mr Ashton said the man had "an extensive family violence history".

"The baby flew into the air"

Dozens of shaken witnesses have gathered at Melbourne West police station to provide statements. One woman, who did not want to be named, said she saw a mother who was pushing her baby in pram struck by the car on the Bourke Street footpath, near Williams Street.

"The baby flew into the air," she said. "The mother was lying on the ground covered in blood."

Police asked the woman and her colleague to get first aid materials and a defibrillator, and she returned to the scene with the equipment. 

She was told that the mother and her daughter were alive one hour after the incident. 

"It was just horrible."

We should point out that while we know a young child has been killed, police have not yet confirmed the child's age.
