The video below is the Associated Press stream of the proceedings in Plymouth County Superior Court. AP carried the trial gavel to gavel from opening statements onward, and its recordings are the most complete and least edited of the several outlets that streamed the case.
Each day is presented with the date, the phase of trial it belonged to, and a brief factual note on the witnesses and events it covered. The notes are navigation aids. They are not a substitute for watching.
A note on day numbers. Outlets numbered the trial days inconsistently. ABC News ran one day ahead of the Associated Press and Court TV throughout. This archive is organized by calendar date, which is unambiguous. Where a day number appears, it is AP's.
