Expert witnesses for the prosecution have challenged the defence's argument that Lindsay Clancy was suffering from postpartum psychosis when she killed her three children in January 2023. The Massachusetts mother is accused of strangling her children Callan, 8 months, Dawson, three, and Cora, five, before allegedly jumping from a second-floor window, which left her paralysed.
On Tuesday, prosecutors called forensic psychologist Kirk Heilbrun and forensic psychiatrist Gregory Saathoff to the stand. Heilbrun testified that he believed Clancy was "criminally responsible" for the deaths, stating she "retained an awareness of the illegality of killing others, including her children." Saathoff noted it was unusual that Clancy had not reported hearing voices before the killings and that they ceased afterwards, also finding inconsistencies in her account.
The defence has argued Clancy committed the acts while experiencing postpartum psychosis, a mental illness that can cause hallucinations and delusions. Defence witnesses, including forensic psychiatrist Dr Phillip Resnick, previously testified that Clancy was "clearly psychotic" and not in control of her actions.
The presentation of evidence is expected to conclude on Wednesday, with closing arguments likely on Thursday. The jury is then expected to begin deliberations on Friday to decide on Clancy's mental state at the time of the children's deaths.
