Both sides agreed that the investigation into the death of Ms. Read’s boyfriend, a Boston police officer, was flawed and plagued by unethical and unprofessional conduct.

Karen Read walked out of court a free woman after more than three years and two trials over the death of her boyfriend, Boston police officer John O'Keefe, who was found on the lawn of a fellow officer's home after a night of heavy drinking.

A jury has found Karen Read not guilty of second-degree murder in death of her Boston police officer boyfriend but guilty of a lesser charge of drunken driving.
