The stepmother of a four-year-old girl allegedly left to die in her cot has been arrested on suspicion of murder.
Willow Dunn's body was found malnourished and decomposing in her bed at her home in Brisbane last Monday, her face partially eaten by rats.
Her father, Mark James Dunn, 43, was charged with murder after he allegedly found the toddler dead two days earlier and didn't call emergency services.
Dunn's partner Shannon White was on Wednesday arrested and is expected to also be charged with murder.
