Police have charged a second person with murder over the death of four-year-old Willow Dunn, arresting her stepmother on Wednesday morning.
Shannon Leigh White, 43, was charged at Morningside police station, minutes from the Cannon Hill home where Willow was found dead on Monday, May 25.
Ms White was not brought into Brisbane Magistrates Court on Wednesday afternoon when her matter was mentioned, but she was remanded in custody, with the matter due to return to court on July 20.
Willow’s father, 43-year-old Mark James Dunn, was charged with murder last week and he was remanded in custody. His matter was also due to return to court on July 20.
Acting Detective Inspector Chris Knight told reporters police were continuing their investigations, which had expanded into New South Wales and South Australia.
“Despite today’s second arrest in this homicide, our detectives are continuing to progress this investigation,” Inspector Knight said.
“We have initiated investigations and inquiries into NSW and, in particular, we have advanced investigations that will continue and progress into South Australia.”
Inspector Knight said the South Australian major crime squad was helping Queensland police with their murder investigation.
“We continue to investigate all aspects of Willow’s health, care, treatment in the days, weeks and years leading up to her death,” he said.
“We know that members of Willow’s family relocated from Adelaide to Brisbane in 2017, and we believe that there’s value in identifying potential witnesses in South Australia.”
