A Colorado mother, who asked for donations to cover her daughter's medical treatment and promoted her "dream list" to perform before she died, was charged with murdering the seven-year-old.
Earlier it was believed that Olivia Gant had died as a result of a terminal illness in 2017.
In a jury charge, the girl's mother, Kelly Renee Turner, 41, also known as Kelly Gant, was charged with 13 criminal charges that included child abuse, theft and charity fraud.
Turner is accused of killing Olivia – not the multiple illnesses she claimed the girl suffered for.

The Make-A-Wish Foundation, which grants wishes to severely ill children, has also paid about $ 11,000 (£ 8,500) for a "bat princess" costume party.
The real cause of Olivia's death is not immediately clear. It was originally attributed to intestinal insufficiency.
Her body was exhumed last year, and an examination found no physical evidence of this disease or other conditions Turner claimed the girl suffered, including seizure disorders and fluid accumulation in deep cavities in the brain.
Olivia's death is now listed as undetermined.
Several doctors interviewed said Olivia did not have a terminal condition. The girl began treatment at the hospital in 2013 after moving from Texas, where Turner's husband was left behind.
The investigation into Olivia's death began after hospital doctors suspected last year after Turner brought in his eldest daughter because of "bone pain," according to the indictment.

During an interview, investigators said Turner spontaneously exposed Munchausen's syndrome by proxy, a psychological disorder in which parents or caregivers seek attention for their children's or dependent's illness and sometimes cause them attention-seeking injuries.
"That was never my case at all," she said in the interview.
During the investigation, authorities separated Turner from his eldest daughter to see if the girl would still report the same symptoms. The daughter has not had any medical problems or pain complaints since October 2018, the prosecution said.
It is not immediately clear how old she is or with whom she now lives.
The daughters were insured by Medicaid, and Turner is accused of fraudulently obtaining $ 539,000 (£ 415,000) assistance from the US government-funded program.
