As a teenager descended into psychosis, killing animals, having visions and hearing voices, her mother consulted a naturopath believing the girl's behaviour was due to a hormonal imbalance, an inquest has been told.
Two weeks after the 14-year-old confessed to her mother she thought about killing people, including her parents, "all the time", the girl killed 10-year-old Biddy Porter at a property in rural NSW.
