Warning: This post features explicit details of child abuse that could be triggering for some readers.
Sanaa Cunningham was only seven years old when she died.
She had a bone-deep cut on her foot and more than 60 scars on her body.
Adelaide-born Lisa Cunningham, 43, and her ex-police detective husband Germayne Cunningham, 39, face execution if found guilty of her abuse, neglect and murder.
Lisa is currently inside the maximum-security wing at Estrella Women’s Jail in Arizona facing lethal injection.
In February 2017 Sanaa was rushed to an urgent care centre due to trouble breathing and later died. A post mortem found her body covered in scars, with more than 100 cuts and bruises.
It confirmed septic shock in the setting of acute bronchitis as cause of death.
The Cunningham's lawyer argues the autopsy examination was unable to determine whether Sanaa died as a result of homicide and has accused police of botching a report that details Lisa's test messages in the lead up to Sanaa's death
The text messages are described as "critical to criminal and medical findings" and will play an important part in their upcoming trial, but the Cunninghams maintain they have been fabricated.
