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.

Jackson pressed McCabe on her testimony from the first trial about the last time she saw Read’s SUV and when she noticed it was gone. McCabe said she could not remember the specific times. “At a bare minimum, you were at the door looking out the window ... four times, correct?” Jackson asked.
