The judge in the criminal case of Lindsay Clancy said on Friday he would declare a mistrial after the jury could not agree on a verdict for the Massachusetts woman accused of killing her three young children in 2023. He then granted the defense an hour to file an emergency appeal before formally declaring. The 12-person jury deliberated for a little over six days, twice telling the judge they were deadlocked on a decision and were sent back for further discussions before ultimately stating they couldn't agree on a unanimous verdict. On Thursday, Clancy's defense attorney Kevin Reddington moved to replace one of the jurors because he claimed they were not following the instructions of the law on reasonable doubt based on a note the jury foreperson had sent stating one juror was holding up the case. The note said, in part, that one juror acknowledged doubt but refuses to apply it to the verdict. It did not say which direction the other 11 jurors were leaning. The judge refused to replace the juror, instead sending them back for more deliberations after repeating instructions on what reasonable doubt means. Nevertheless, the case could end in a mistrial on Friday. What happens next is ultimately up to the Plymouth County District Attorney's office based on a number of factors. The jurors will be polled individually to determine where the case was leaning, which could bring up the potential for a plea deal. The district attorney's office might also consider whether or not Clancy's family wants to go through another trial, and, if so, she could face different charges. Clancy was originally charged with first-degree murder after her then-husband Patrick Clancy found their children - 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan - dead in the basement of their family home in Duxbury on the night of Jan. 24, 2023.
