Defense attorneys for Karen Read rested their case Wednesday, bringing her retrial for the death of her Boston police officer boyfriend one step closer to its blockbuster conclusion.

Karen Read's defense rested its case after a biomechanical engineer told jurors John O'Keefe's injuries were inconsistent with a car crash.

After nearly two months of testimony, Karen Read’s retrial for the murder of her boyfriend John O’Keefe is in its final days. The defense has now rested its case, without Read taking the stand. NBC News’ Emilie Ikeda reports.

CNN highlights about a dozen witnesses called over the last eight weeks, whose testimony illuminated key pieces of the theories presented by prosecutors and Read’s defense.
