The Karen Read murder case ends in a mistrial. Prosecutors say they will try again

Prosecutors say they intend to retry Karen Read on charges that she killed her Boston police officer boyfriend by striking him with her SUV. The judge declared a mistrial Monday after jurors were unable to reach a verdict following a two-month trial. Read had been charged with second-degree murder in the 2022 death of Officer John O’Keefe. The 16-year member of the Boston police was found unresponsive outside the Canton home of another officer. An autopsy found O’Keefe died of hypothermia and blunt force trauma. Defense attorneys argued police framed Read.
