Richard Claflin

Richard Claflin testified for the prosecution on Day 28 about leading the post-bombing video canvass with Boston Police Sergeant Earl Perkins. The FBI special agent described how investigators gathered recordings around Boylston Street, collecting approximately 35 to 40 pieces of video evidence on the first night. He explained that a city business list and investigators' observations became checklists for the canvass.

Claflin described designated intake locations, collection records, chains of custody, and computer specialists' work with material arriving on different devices. The team moved from the Westin Hotel to the Lenox Hotel on Tuesday, and the search expanded toward Storrow Drive and Massachusetts Avenue on Saturday. He said the collection and logging he observed appeared to follow FBI procedures.

Claflin qualified his recollection of some collection details and distinguished his responsibilities from technical video extraction, which he said was outside his expertise. His testimony explained the origins and handling of the recordings, not what they showed or an identification of either suspect. No numbered exhibit was offered or admitted during his examination, and defense counsel David Bruck declined to ask questions.
