Karen Read's defense presents expert testimony that Officer O'Keefe's fatal injuries resulted from falling backward, with facial wounds caused by a separate impact.

On Friday, the jury heard lengthy testimony from an accident reconstruction expert first hired by the federal government, who is now retained by the defense, about the damage to Read’s SUV. The expert will continue his testimony Monday morning. The trial resumes at 9 a.m. Monday, which marks the start of the 8th week of testimony.
