Read is accused of backing her SUV into her Boston police officer boyfriend, John O’Keefe, and leaving him for dead.

“I don’t believe that’s consistent with the evidence and what occurred,” Rentschler replied. Rentschler was the final defense witness, just as he was during Read’s first trial last summer. After he left the stand, Jackson announced Read’s defense would rest its case subject to a final ruling on evidence.

Karen Read's defense could rest its case on Wednesday after biomechanist Andrew Rentschler from ARCCA is expected to complete his testimony inside Norfolk Superior Court in Dedham, Massachusetts. Rentschler testified that John O'Keefe's injuries were not consistent with being hit by a vehicle.
