'This is what happens when soft tissue hits solid ground'

After a surprise start to the day in Karen Read's murder retrial, a brain surgeon broke down the injuries John O'Keefe sustained, what may or may not have caused them and why they didn't kill O'Keefe right away. Martin Radner, of the "Brother Counsel" YouTube page, shares what the surgeon's testimony solidifies, and what he still leaves open. Plus, more on the courtroom being cleared for Judge Cannone to question jurors, what a forensic analyst testified about the debris found on O'Keefe's clothes and a former state police officer on how Michael Proctor's name keeps coming up and Sgt. Yuri Bukhenik's testimony.    You can watch the TV version of this episode — and all the others, as well as video from court as it happens — on our YouTube page.
