Judge declares a mistrial in Lindsay Clancy murder trial | What happens next

It was a dramatic day in a Massachusetts courtroom as the Lindsay Clancy trial came to an end. Late this afternoon, the judge formally declaring a mistrial, but not before giving the defense a chance at an emergency stay. ABC's Olivia Rubin has the latest from outside the courthouse in Plymouth. A dramatic end to the Lindsay Clancy murder trial. I'm going to declare a mistrial. After jurors said they were deadlocked for the third time since Tuesday. It is with a heavy heart that we report we are unable to come to a unanimous decision. In a last-ditch effort, the defense submitting a request for an emergency stay to the Massachusetts Supreme Judicial Court, eventually being denied. The deliberations leading to major tensions in court all said to be surrounding a single juror. Clancy's attorney saying one holdout is refusing to follow the judge's instructions on reasonable doubt, reading this note sent in from the foreperson yesterday. Juror number, which I will not mention, and I quote, has made statements acknowledging doubt, but refuses to apply it to the verdict as the law states. The judge denied to dismiss the juror as the defense requested and also refused to question that juror individually. Clancy had pleaded not guilty to the charges related to the 2023 killings of her three children. The jury considering five possible verdicts, including not guilty due to lack of criminal responsibility. During the trial, defense attorneys arguing she was suffering from postpartum psychosis, a severe mental health condition they say essentially left her legally insane. But prosecutors arguing Clancy acted intentionally, rationally, and swiftly to kill her children. Now a mistrial could mean this trial starts all over again. They'll be back in court at the end of the month to discuss those next steps. In Plymouth, Massachusetts, Olivia Rubin, Channel 6 Action News.
