For weeks, all appearances were that prosecutors would call witnesses as part of a brief rebuttal case in the Karen Read retrial, giving them the opportunity to get the last word after damaging testimony from expert witnesses for the defense.

Karen Read's defense concluded with expert witness Dr. Andrew Rentschler testifying that Boston cop John O'Keefe's injuries were inconsistent with being struck by Read's SUV.

For the second time in a week, Judge Beverly Cannone denied Karen Read's attorneys' request for a mistrial after they accused the prosecution of misconduct.

Both sides in Karen Read’s murder retrial appeared in court Thursday for a hearing before they deliver closing arguments to jurors on Friday. The hearing is known as a charge conference, where the parties hash out instructions the jury will receive before they start deliberating. Jurors weren’t present for Thursday’s proceedings.

Jurors heard from a trio of witnesses on Monday, including an accident reconstruction expert and a medical examiner hired by the defense. The medical examiner resumes her testimony under direct examination Tuesday morning.

Karen Read's defense rested its case Wednesday after a crash expert said that he does not believe John O'Keefe was hit by a vehicle.
