Prosecutors have called on the state's highest court to allow them to retry Karen Read for murder in the death of her Boston police officer boyfriend, arguing against defense claims that jurors had reached a verdict against some of her charges before the judge declared a mistrial.

Read’s attorneys argue she is being framed and that other law enforcement officers are responsible for O’Keefe’s death. A judge declared a mistrial in June after finding that jurors couldn’t reach an agreement.
