Sophie Wang: Mother Yingying Xu may never face trial after allegedly murdering daughter in Carrara, Gold Coast

A mother accused of murdering her infant daughter can no longer stand trial for the alleged crime due to a mental illness.

Yingying Xu, 46, has been charged with the murder of her 10-year-old daughter Sophie Wang at their Emerald Lakes house in Carrara, on the Gold Coast, Tuesday evening.

Sophie, a fifth-year student at Emmanuel College, was found by her father at 6pm with her throat cut. Emergency services were unable to save her.

Xu, who was arrested at around 10.30pm and charged with the murder, may be treated in the mental health court, legal sources told the Courier Mail.

The court determines whether a suspect was of sound mind at the time of the alleged crime and whether he/she can be prosecuted.

Police have not confirmed whether Xu has a history of mental health issues, but she did post three videos on TikTok in which she mumbles in Chinese about religion on the day she killed her daughter.

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 been conducted by the experienced Queensland police. detectives have described as one of the ‘most confronting‘ they have ever seen.
