Mum accused of murdering toddler daughter due in SA court

A South Australian woman accused of murdering her two-year-old daughter is to face a hearing on her mental fitness to plead to the charge.

Catherine Anne Pallin, 40, is accused of murdering Ayeesha Aqua Pallin in July last year.

The toddler's body was found on a rural property in the Adelaide Hills.

The Adelaide magistrates court has previously been told a psychiatrist concluded Pallin "was unable to reason, with a moderate degree of sense and composure, about the wrongfulness of her actions".

She opined Pallin was suffering from a mental impairment at the time of the offence, that would "render her incompetent" under the law.

Pallin, who is on home detention bail, will face a judge-alone trial in the Supreme Court on Thursday in relation to her mental fitness to plead.
