Karen Read is charged with killing her police officer boyfriend John O’Keefe. She is being retried after her first case ended with a deadlocked jury last year.

“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.
