The youngest person to die during the Bourke St rampage in Melbourne's CBD has been remembered by his parents as the most "beautiful, loving, happy, and perfect little baby".
Three-month old Zachary Bryant died at Melbourne's Royal Children's Hospital from the injuries he suffered when his pram was struck by a car allegedly being driven by Dimitrious "Jimmy" Gargasoulas on Friday afternoon at Bourke St Mall.
His sister Zara was also injured but is in a stable condition at the same hospital where doctors and nurses fought so hard to save Zachary.
Their parents, Matthew and Nawwar Bryant, released a tribute about their son where they spoke movingly about the last three months they'd spent with him.
"He was the most beautiful, loving, happy, and perfect little baby we were so lucky to be gifted with," they said.
"He was the light of our lives constantly filling our days with smiles and laughs.
"He leaves us with the best three months and 14 days of wonderful memories spent in this world."
The tribute went on to say: "Zac, Mummy and Daddy love you very much and always will."
The parents said their "beautiful Zara" was still fighting and was stable.
They also paid tribute to the support they'd received from "everyone" since the mall carnage.
Of the incident itself, the tribute simply said a "man drove through Melbourne city killing and hurting people, including our two-year-old toddler Zara and our three-month-old son Zachary".
Haunting images of Zachary's pram turned over on its side after being struck by the red Commodore sent shockwaves around Australia on Friday afternoon.
Witnesses said a woman could be heard screaming "where's my baby" in the chaos-filled moments after the car raced along the packed pedestrian mall.
Nethra Krishnamurthy, a young mother, has woken from the coma she has been in at the Alfred Hospital's intensive care unit.
Her horrific injuries include broken bones and a fractured spine, a punctured lung and damage to her liver and kidneys.
She had been breastfeeding her baby only a few minutes before she too became a victim of the car rampage. The Herald Sun reported Ms Krishnamurthy had only returned from maternity leave to her IT support job at Mexia Consulting in the city.
She was on her way back to work after visiting her eight-month old at daycare.
Her husband Mohan Kumar has kept a vigil at her bedside.
Mexia director Mathew Coleman said Ms Krishnamurthy didn't have any family in Australia, and staff were rallying around them.
