Vigil for baby Queenie
Hundreds gather to remember two-month old baby Queenie who was killed in an alleged stabbing attack as her mother and grandmother recover in hospital. Nine News
Queenie didn't last the afternoon, passing away from the injuries she suffered lying helpless in her bassinet, while her grandparents underwent life-saving surgery.
Her 28-year-old mother, who ran screaming for help down the normally quiet street of the family's home in Brisbane's south, was not as badly injured but still needed surgery.
Her husband, Tenglong Xu, was working at the time and had to find out about the bloodbath through police.
On Friday, 52-year-old Mr Cao was charged with one count of murder and two counts of attempted murder in a bedside hearing at the Princess Alexandra Hospital.
All three injured family members remained in the PA Hospital on Sunday evening, Mr Cao under police guard, but had improved to a stable condition.
He and Mrs Fu were believed to have flown to Brisbane from China at the start of December to help their daughter care for her newborn baby, also known as Qianqian.
It was understood Mrs Cao could be released in the first half of this week, pending physical and mental assessment by doctors.
The sickening stabbing in the affluent suburb of Parkinson shocked neighbours and community members.
More than 200 people, most of whom didn't know the family, gathered in the normally idyllic park across the road from the family's Watheroo Place home for a candlelight vigil on Thursday night.
Mr Cao was remanded in police custody at the hospital for for committal mention on February 8.
