Karen Read addresses a crowd outside of a Massachusetts courthouse after being found not guilty of the most serious charges in her high-profile murder retrial Wednesday. In their fourth day of deliberations, jurors acquitted Read of second-degree murder and vehicular manslaughter in the death of her boyfriend, Boston police officer John O’Keefe. She was convicted of driving under the influence of alcohol. Karen thanked her supporters and says, ‘No one has fought harder for justice for John OâKeefe than I have.’
