A jury has been selected for the retrial of Karen Read, charged with second-degree murder in the death of her boyfriend, Boston police officer John O’Keefe, who was found dead in January 2022 due to hypothermia and blunt-force trauma. Read’s first trial ended in a hung jury last summer, with allegations of law enforcement misconduct surfacing during the proceedings. The retrial, which begins with opening statements on Tuesday, follows a controversial investigation and prosecution, including claims of evidence manipulation by the lead investigator.
