Karen Read faces retrial for second-degree murder in the 2022 death of her police officer boyfriend.

Karen Read faces second-degree murder charges in a retrial for allegedly hitting her boyfriend, Boston police officer John O'Keefe, with her SUV and leaving him to die in a snowstorm in 2022. Prosecutors argue that the evidence, including broken taillight pieces and phone data, supports their case. The defense claims the evidence could have been planted by law enforcement and that Read was used as a scapegoat. The first trial ended in a hung jury.
