Lindsay Clancy's former mother-in-law testified at her murder trial that Clancy was "begging for help" in the period before she killed her three young children in January 2023. The testimony is the latest in a string of witness accounts describing a marked deterioration in Clancy's mental health following the birth of her youngest child, forming a key part of her defence's case that she was suffering postpartum psychosis at the time of the killings.

Susan Clancy described insomnia, appetite loss, anxiety and sadness in her former daughter-in-law, calling her a "very nurturing, very loving" mother who was actively seeking medical help. Clancy, 36, does not dispute strangling Cora, 5, Dawson, 3, and Callan, eight months, with fitness bands before jumping from a second-floor window, an act that left her paralysed; she has pleaded not guilty to first-degree murder, while prosecutors argue the killings were a calculated act rather than the result of psychosis. Other relatives, including Clancy's mother and sister, have testified that she reported thoughts of harming her children and daily suicidal thoughts in the month beforehand, and had briefly checked herself into a psychiatric hospital before the deaths.
