Besides the trunk, they screwed up the use of the video. All digital videos have a time stamp as part of the recording. Of course, that also assumes the owner's of the camcorder bothered to set the time in the camera.
It is the fact that they didn't even bother to mention it. Then again, if they had set the time on the camera, the case would have been solved 6 months ago and it would never have gotten to be this particular episode.

Gotta love how stuff is purposely left out in order to make an episode work.
