Patrick Clancy testified Tuesday in the murder trial of his ex-wife, Lindsay Clancy, who is accused of killing their three young children in 2023. He described her worsening mental state, saying she 'kept getting worse and worse' and experienced a 'big spiral' while taking the medication Seroquel. Clancy said his ex-wife had intrusive thoughts about harming the children before the deaths. An expert witness also testified, stating that one aspect of the case 'scared me.' The trial, taking place in Massachusetts, continues as the prosecution presents evidence of the alleged killings. Patrick Clancy’s testimony offered a personal account of the family’s struggles with mental health issues leading up to the tragedy. The defense is expected to argue that Lindsay Clancy was suffering from severe mental illness at the time of the incident. The case has drawn widespread attention due to the nature of the allegations and the history of the couple’s efforts to seek help.
