Jennifer McCabe is set to take the witness stand in Karen Read's second murder trial. 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.

Testimony in the retrial of Karen Read continues Wednesday with Jennifer McCabe, a witness for the prosecution.

McCabe’s direct examination continued with prosecutor Hank Brennan before the defense began cross-examining her.
