Possible explanation for bizarre behavior on camera:
1) Perp is startled by camera
2) knows someone might get an alert and look at the camera feed
3) has to think fast; blocks camera with hand (back of hand because he was grasping something?)
4) realizes anyone looking will still see a hand
5) decides to use flowers so that if someone looks, it looks natural
That's still not a good or likely explanation, but it's all I've got. Other idea is a calling card or it was meaningful to the perp (mentally ill?).
