Karen Read’s second murder trial was a rematch for the lawyers after the first ended in a hung jury last year. CNN correspondent Jean Casarez answers key questions about the case after Read was acquitted of murder Wednesday.

Karen Read was found not guilty for the 2022 death of her Boston police officer boyfriend John O’Keefe, more than one year after her first trial ended in a hung jury.
