 No verdict in the trial of Karen Reid, who's suspected of killing her boyfriend, who was a Boston police officer, WBZ's Emma Friedman. Your service is complete. I'm declaring a mistrial in this case. The Commonwealth says they do plan to retry the case against Karen Reid with a new jury. Reid was charged with second-degree murder. Prosecutors saying she killed her boyfriend, Boston police officer John O'Keefe, by hitting him with her car in a jealous rage. The defense has refuted this since day one, saying Reid is being set up by law enforcement. Just in, Hurricane Beryl.
