About
Matthew Isgur authenticated MIT surveillance footage during his direct examination for the prosecution on Day 31. He maintained MIT's surveillance system and testified that its recordings and timestamps were accurate. He explained the North Court camera's location and authenticated an edited composite and a close-up video, both admitted without objection and played in court.
During playback, Isgur identified Sean Collier's cruiser and described two figures entering from Main and Ames, returning along the same route, and leaving the screen by 10:26 p.m. He said no other cameras captured the cruiser at that position. Asked about a later figure near the cruiser, he initially said the image was dark, then said he could see it after further playback.
Two additional videos were admitted: footage Isgur described as showing a car fleeing Ames Street and footage from the same camera exactly one week later at approximately the same time. The government did not play those two videos at that time.
