For some reason, the video clip showing Meredith returning home had the camera time clipped from the image. Here is a frame from the original video that does show the timestamp.
From cell phone times and images taken the next day, we know the camera clock is 10 to 12 minutes slow. The prosecution claimed it was 10 minutes fast, but at that time Meredith was still with her English friends and Amanda was talking Jovana Popovic at Raffaele's place.
The person in this photo is almost certainly Meredith. The 9:01 to 9:03 time is right for a walk from where she left her friend Sophie about 5 minutes before 9 pm. Also, the only reason to cross the street here is to go to the cottage. Walking past the cottage driveway a pedestrian would have to walk in the traffic lane with no place to go if a car came along.
