A PREGNANT mum and her unborn baby have tragically died after she was smashed in the head with a piece of concrete in a shocking unprovoked attack.
Dianne Miller, 30, was at the car park of Waterford Plaza Shopping Centre in Perth, Australia with her partner when she was attacked.
It is believed the pair got involved in an argument with a group of teenagers.
A 17-year-old is said to have thrown a piece of concrete at the car, leaving the mum unconscious and causing her a heart attack, police allege.
She was rushed to the hospital but doctors said she and her baby were not expected to survive the injuries.
Despite efforts from onlookers and paramedics, the mum’s injuries were severe.
Diane, who was five months pregnant, had been fighting for her life at the Royal Perth Hospital but sadly could not be saved.
The woman leaves behind her partner and an 8-month-old son Lloyd.
Her brother Malcolm Clifton confirmed her death to NITV News.
Speaking from the hospital, he said: “Everyone’s destroyed.
“We just lost our world… the baby passed away too.”
The mum’s devastated brother described his sister as “one of a kind, kind to everybody, good-hearted, with good morals and well-respected.”
Cops described the incident as “senseless” and “unprovoked”.
Inspector Brett Baddock of the Cannington District Office told 7News: “From what we can gather, the woman was a passenger in a car that was stopped in the car park.
“Her partner then became involved in the scuffle … The parties were not known to each other.
“This is, quite simply, senseless violence by a bunch of teenagers.
“From what we can gather, it’s unprovoked. I think they’ve gone out looking for trouble and they’ve found it.”
West Australian Premier Mark McGowan branded the attack as “tragic” and “beyond description.”
He said: “It’s one of those things that is just beyond description that this could happen to someone.
“It’s all very tragic, very very tragic, and I think the family are obviously going through a very difficult period.”
WA Police have launched a homicide investigation.
