Court was barely underway on Day 20 of the Karen Read murder trial when everything came to a screeching halt. Judge Beverly Cannone suddenly cleared the courtroom, including the press, to privately question each juror one-on-one. The reason? A mysterious “issue” no one’s allowed to discuss. Once court resumed, it was a day packed with expert testimony. A neurosurgeon said John O’Keefe’s fatal head injury was classic blunt force trauma — not a bat or weapon. And a forensic scientist broke down red plastic and glass fragments, suggesting they could have come from Karen Read’s SUV.
