Karen Read Trial: Key Testimonies and Cross Examinations Unfold

During the Karen Read murder trial, experts testified about her blood alcohol level on the night John O'Keefe died, estimating it could have been between 0.135% and 0.292% at the time of the incident. The defense argues the estimation is unreliable and claims Read is the victim of a law enforcement coverup. Testimonies also revealed details about Read and O'Keefe's tumultuous relationship and the circumstances surrounding O'Keefe's death.
