Karen Read was acquitted in the killing of her Boston police officer boyfriend John O’Keefe on Wednesday, vindicating a defendant who had claimed to be the victim of a sweeping cover-up across two divisive trials.

A jury cleared Karen Read of the three most serious charges brought against her, second-degree murder, manslaughter while operating under the influence, and leaving the scene of a crash resulting in death.

After Karen Read was found not guilty of murder and manslaughter in the death of her boyfriend, Boston police officer John O'Keefe, cheers erupted outside the courthouse in Dedham, Massachusetts. One of O'Keefe's friends from college said the celebration was "disgusting."
