Dever, who worked in Canton at the time of Read’s arrest, was called by the defense Monday morning. On the stand, she faced aggressive questioning from Alan Jackson, one of Read’s lawyers, about a statement she made to federal investigators looking into the death of Read’s boyfriend, John O’Keefe.

Dr. Marie Russell took up most of the day on the stand. She was the same dog bite expert from Karen Read’s first trial. Two other witnesses were called by the defense today, including a former Canton Police officer, Kelly Dever, who was a reluctant witness.
