Karen Read pleaded not guilty to murder charges in the death of Boston police officer John O’Keefe and is facing a retrial after a jury was unable to reach a verdict last year.

On Thursday, jurors heard testimony from a doctor with the state’s Chief Medical Examiner’s Office about the injuries to O’Keefe and the conclusions of the autopsy she performed. Testimony resumes when the court is back in session at 9 a.m. This post will be updated as testimony gets underway.

DEDHAM, Mass. — An important ruling was made by Judge Beverly Cannone on day 17 of testimony in the retrial of Karen Read. Right after the jury was sent home for the weekend, Cannone announced that she’s not going to penalize the prosecution for entering new evidence.
