Detectives are investigating religious TikToks posted by a mother accused of slitting her daughter’s throat on the same day she allegedly murdered her.
Yingying Xu, 46, is alleged to have murdered her daughter Sophie Wang, 10, at their Emerald Lakes home in Carrara, on the Gold Coast, on Tuesday.
Sophie’s father, Yun Wang, a science professor at Griffith University, arrived home to find his daughter. He called 911, but despite the efforts of emergency services, she could not be saved.
Xu, 46, was arrested more than four hours later – at 10:25 p.m. – on a nearby street and has since been charged with murder.
Earlier on Tuesday, Xu posted three videos on TikTok in which she mumbles in Chinese about religion.
In the excerpts, Xu talks about Christianity and how the “Trinity” is the “one true God” and “Jesus is the incarnate son of man.”
The videos will form part of the investigation into the case, which has continued over the years. detectives have described as one of the ‘most confronting‘ they have ever seen.
The death of the fifth-grader has shocked the close-knit community in the area, including her school, Emmanuel College, which is just 600 metres from her home.

Amanda, who lives across from Xu-Wang’s house, describes Sophie as a “very friendly girl.”
“She was in the same class as my grandson. He always talked about her and they got on really well,” Amanda told Daily Mail Australia.
“They were in the orchestra together. My grandson played the violin and she played the piano and recorder.”
‘I could always hear her making music from the street.
“She always walked to school and back. She was very friendly and always said hello. A very friendly girl.”
Amanda, who has lived in the neighborhood for 12 years, says she didn’t notice anything unusual on the street until police swarmed the street around 6 p.m.
It wasn’t until the incident hit the news later that evening that she learned what had happened.
“I didn’t know the man, but I saw the woman walking in and out,” Amanda said.
‘She was very introverted. If you walked past her, she wouldn’t even say hello or anything.
“The whole community is in shock today.”
On Wednesday, community members came en masse to the house to lay flowers.

Classmate Oliver Hayes, 11, who arrived at the house with his mother and other school friends, said Sophie was academically talented.
“She was one of the smartest kids in our school,” Oliver told Daily Mail Australia.
“There are so many words to describe her. She was very kind, she really cared about people and she was very nice.”
The tragedy has also shocked staff at Griffith University, where Prof. Wang works in the Department of Chemistry and Forensic Sciences and specializes in renewable energy.
Two male colleagues of Prof. Wang arrived at the house with food on Wednesday afternoon, but were turned away by an officer because their father was not there.
The university provides support to Prof. Wang and his close colleagues.
“We are deeply saddened by the tragic passing of the daughter of a valued member of the Griffith community,” the university said in a statement.
“Our thoughts are with the family and friends at this incredibly difficult time.”
Emmanuel College Principal Dan Brown wrote a letter to the school community on Wednesday morning to express his condolences.
“It is with a heavy heart that I must inform you of a tragic incident that occurred last night at a home in Emerald Lakes, resulting in the death of one of our beloved students,” the letter reads.
