hours of video we have watched. let's look at the first one. it shows kendrick walking in from the white side of the screen there behind another student and as soon as he runs out, that student disappears and a couple other students disappear -- appear, rather. it's from one image to the next with no explanation of how those students got to that position or where the student at that red shirt went. we blurred their faces because they are minors in this video and the next. let's go to the next one. you can see kendrick at the bottom right of the screen. he's walking at first and then he runs out of the frame and just like the first video, other students just appear. no explanation of how they got to that point. you don't see them walk in. we have not ed edit these videos to put one image next to the other. this is how we received them from the sheriff's office today. >> so the video seems to be jumping around. you are saying those aren't edits. i assume that's a motion sensor camera, is that the way it works, it may take a few seconds for an image to register? >> reporter: that was our first
