Prosecutors have finished presenting their case in the emotionally charged trial of Lindsay Clancy. The prosecution rested its case Monday after three weeks of testimony in the trial of the Massachusetts mom who has admitted killing her three young children. Clancy's lawyer now gets his chance to call witnesses. Clancy's lawyer says she shouldn't be held legally responsible for murder because she was in the grip of postpartum psychosis when she killed her children before trying to kill herself. Prosecutors say Clancy acted intentionally. They say she contrived to get her husband out of the house on errands the day of the killings in 2023.
