Lindsay Clancy continues to make her insanity defense in ‘America’s saddest murder trial’ following a day of gripping testimony from her psychologist.

The former nurse, 36, is on trial for the murders of her three children, Cora, five, Dawson, three, and eight-month-old Callan, at her home in Duxbury, Massachusetts, in 2023.

She strangled her children with exercise bands and then allegedly attempted to kill herself, but her efforts failed and left her paralyzed and in a wheelchair for life.

Clancy's psychologist, Dr Paul Zeizel, told jurors on Tuesday about the moment she told her husband about the 'male voice' in her head that ordered her to kill her children, then herself.

Dr Zeizel testified that he visited Clancy in the hospital in the days after the killings, and she borrowed his phone to call her husband, Patrick.

That was when she told him that she had heard a man's voice telling her to kill the children and herself.

The prosecution rested its case against Clancy on Monday after using the first three weeks of the trial to argue the killings were intentional and well planned, not the work of someone who had lost control.

Clancy has admitted to killing her children but pleaded not guilty to murder by reason of insanity, citing postpartum psychosis, and is seeking to be committed to a state mental health facility rather than a prison sentence.
