Karen Read is seeking to delay a wrongful death lawsuit until her criminal trial in connection with the death of her Boston police officer boyfriend is done. The lawsuit filed last month by the family of John O’Keefe blames his death on Read, and also on what the lawsuit describes as negligence by bars that continued to serve drinks to her despite signs she was drunk. It says the first bar served her seven alcoholic drinks in about 90 minutes the night of Jan. 28, 2022, and that Read carried the last drink into the second bar, where she was served more alcohol.
