On a snowy January morning in 2022, Boston police officer John O’Keefe was found dead outside a fellow officer’s home and his girlfriend, Karen Read, was charged with hitting him with her SUV and leaving him to die. Prosecutors say it was a drunken hit-and-run. The defense claims a cover-up inside the house and a rush to frame her. What happened in those early morning hours has divided a community and turned this case into one of the most explosive courtroom battles in Massachusetts.
