Prosecutors retrying Karen Read in the killing of her boyfriend are laying out a minute-by-minute accounting of what they say happened at the suburban home of a fellow law enforcement officer where John O’Keefe was found unresponsive on a snowy morning three years ago.

Since her arrest, two narratives have since emerged. The prosecution alleges that Read killed O'Keefe by backing into him with her SUV and leaving him to die after a fight. Read's defense team argues that the police and other parties have colluded to frame Read for his murder.
