Testimony has wrapped in the case against Massachusetts mom, Lindsay Clancy, and closing arguments are set for Thursday. The final witness was one of three rebuttal witnesses called by the prosecution, all of whom testified that Clancy was not suffering from postpartum psychosis at the time she strangled her three young children to death. The defense spent hours attempting to discredit the senior forensic psychologist for the FBI’s Behavioral Analysis Unit, who told jurors Clancy was in control and aware of the illegality of her actions.
