Nine News reporter on the horrific death of a 10-year-old 03:06

This story out of the Gold Coast today, truly horrifying. Horrifying. It stopped me in my tracks when I heard it. A mother has been charged with the murder of her 10-year-old daughter. 10-year-old daughter had her throat slashed. Seriously shocking stuff. Well, Jacob Chico, he's from Nine News in Queensland. He has the story. He's on the line for us. Jacob, g'day. G'day, Chris. What's the latest from police?

Police, they provided an update to us a couple of hours ago. Now, this one, as you said at the start there, deeply distressing. It's one that's really shocked seasoned officers. They got the call just after 6 o'clock last night and what they were confronted with here was just truly horrific. They've described 10-year-old Sophie Wang as having injuries consistent with that knife attack, as you mentioned, plus more.

So they're now investigating whether there were any warning signs here, trying to really piece together if anything could have prevented this one. Carrara on the Gold Coast is someone who lived there for 12 months. Pretty tight-knit little community. Carrara, how's everyone been?

They're not good. Tight-knit community here. It's at Emerald Lake, just across the road from Emanuel College, for people that know the Gold Coast well. It's one of the elite private schools here. Sophie went to school across the road. When I say across the road, her home's literally metres away from her school. And what we're seeing is the school community now come here to the crime scene where forensic crews are still working.

People are dropping off flowers. They're leaving messages for Sophie. Her school has paid tribute to her. People are very emotional. They're really like everyone here, trying to understand what can possibly lead a mother to allegedly do this to her own daughter in such an awful way. Any more information as to potential motive or if there was anything in the background that could possibly have sparked such an horrific attack, obviously an alleged horrific attack?

Clearly the main part of this investigation now is the mental health of Sophie's mum, who we can confirm fronted court.

this morning in Southport. We understand that she has extensive mental health issues and police are now investigating social media posts that Sophie's mum put up 24 hours ago, 48 hours ago, quite eerie social media posts.

That's really the line of inquiry here, her mental health and whether there was a mental health order in place, whether she should have been receiving treatment. Something's happened here clearly that just shouldn't have. Clearly there's been a fundamental failure of the system, but that doesn't make it any less tragic. It's just horrific beyond words. Jacob, I appreciate you coming on. Thanks so much. Thanks, Chris. That's Jacob Chico from Nine News in Queensland.
