The neighbor who was a Canton PD officer (I don’t remember if he was retired or current) told KR’s private investigator that there was nothing picked up on the ring cam. Lots of differing opinions on whether the ring cam would have captured anything. AFAIK, neither the defense nor CW tried to get the video, although I could be wrong.
The library video, on the other hand, is much more sketchy. Two minutes of the video were ‘missing’ when turned over to the defense. The CW insists that they did not alter it in any way, which begs the question of why that data at that particular time is gone…
