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.

Boston Police Officer John O'Keefe, his girlfriend Karen Read and a group of other friends, including fellow officers, went out drinking at C.F. McCarthy's bar in Canton, Massachusetts at around 9 p.m. A major snowstorm had begun.

A jury found Karen Read not guilty of second-degree murder Wednesday in the death of her Boston police officer boyfriend but guilty of a lesser charge of drunk driving. The jury handed down its decision after deliberating for at least 22 hours since Friday.
