Karen Read announced Tuesday that she would not testify in her murder retrial, after weeks of saying that she hadn't made up her mind on whether she would do so.

Tuesday marks Day 30 of witness testimony in Read’s second trial. Attorneys are expected to argue motions, including what the defense’s next ARCCA witness will be allowed to testify before Dr. Elizabeth Laposata returns to the stand.
