Karen Read lawsuit murder trial John OKeefe.

Karen Read, who was found not guilty of charges related to death of her boyfriend, has filed a lawsuit accusing members of the Massachusetts State Police and several others of targeting her and failing to investigate the real killers. Read walked out of court earlier this year 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. The lawsuit filed in Bristol Superior Court Monday makes many of the claims her defense team made during the trial, namely that O’Keefe was in fact killed by colleagues, followed by a vast cover-up.
