No. 1. The white box truck composite is reported to have come from eye-witness accounts, not surveillancve video tapes. It has never been reported that the composite is based on video tape(s). If there were such a tape(s) they would have published an image of it -- no reason on earth not to. And if they had such a video and it showed a license plate or other ID on a windshield or something, then they'd probably already have the driver and passenger, if there is one.
No. 2. The only people who could have "planted" the tarot card -- other than the mean individual who is the killer -- would be the cops because they zoomed in on the wooded area immediately -- I watched it happen in real time on TV. There was no time for some other nutcase to "plant" the card.
Use some common sense, people.
