I asked another reporter about the red bag with money into the manila envelope and the car and he verified.
So not just a manila envelope covering the red bag, or placed over the red bag, to sort of make the red bag on the seat less visible? IOW, the red bag holding the money was placed inside a manila envelope?

At the victim's request, Wallace placed the money, which was in a red bag covered by a manila envelope, on the seat of a red sports car in the garage.
