 I'm John Saucier. The jury remained deadlocked in the murder case of Karen Reed, accused of killing her boyfriend, a Boston police officer named John O'Keefe. Judge Beverly Cannon ordered the jury to deliberate once more, but when they still couldn't come to a verdict, she made the announcement that... Your service is complete. I'm declaring a mistrial in this case. Officer O'Keefe is a 16-year member of the police force in Boston. An autopsy found he died of hypothermia and blunt force trauma.
