Ms Broadbent’s two-year-old could already count and sing her ABCs – testament, neighbours said, to the children’s “fantastic mum”.
Those neighbours watched over her two young children on Saturday night as their mother delivered a third child via caesarean section and later died from her injuries.
Police allege the 35-year-old man had threatened Ms Broadbent outside her home on Kiwi Retreat in Keilor Downs about 1pm on Saturday.
The threats then “continued in a car” before the 32-year-old fell out of the back seat onto the road as it turned a corner, a police spokeswoman said.
It is unclear how she was ejected from the vehicle.
The man was taken into custody on Saturday.
Ms Broadbent’s newborn baby remains in a critical condition at the Royal Women’s Hospital.
A media spokeswoman for the hospital could not confirm the status of the child’s condition on Sunday afternoon.
Footage from the scene on Saturday showed blood and belongings scattered near the corner of the street where Ms Broadbent was treated by paramedics.
Neighbours Bernadette and Brian Hall said they’d lived on Kiwi Retreat, two houses away from Ms Broadbent, for about seven years.
They’d seen her now and again, but never really interacted until she was sold a “dodgy car” last year and Mr Hall helped her out.
Last Friday, Ms Broadbent finally bought a new car, “something finally for her”.
The distraught couple watched over their neighbour’s young children as the tragedy unfolded on Saturday.
“She was a beautiful mother, the kids just loved her,” Mrs Hall said. “They’re just lovely kids.”
Mrs Hall said Ms Broadbent had been about six months’ pregnant.
The couple is still caring for her dog, Ollie. The children are now with Ms Broadbent’s parents.
A floral tribute for Ms Broadbent has continued to grow throughout the day as those who knew her come to pay their respects.
Mr Hall was the first to lay flowers at the street’s corner.
“We’ve got a lovely garden so we thought we’d put a few flowers down. People have been coming throughout the day and it’s grown,” he said.
Mr Hall said it was upsetting to see Ms Broadbent’s now vacant house.
“It’s a rental property as far as I’m aware, so I’m not sure what happens now, but I’ve never seen it like this. The curtains are gone from the front, so I’m not sure what happened there, but you can see right through,” he said.
“I’m not sure what happens with the car either. She was so excited about that car. She’d saved and saved for it and finally bought it just last week. It’s sad to see it sitting there.”
Ms Broadbent’s devastated brother Paul said his sibling was “the best sister anyone could have”.
“I just can’t believe it, my baby sister,” he said.
“We had our ups and downs, as brothers and sisters do. I always loved her,” he said.
