They arrested a woman at the trailer of the seller....But if the truck's out on the street, anyone could have shoved it in, late at night...I didn't think of that. Here's hoping the identity of the victim and of the killer (if it was murder) is cleared up quickly.
Shoving it in late at night would guarantee that it will be found pretty soon - as soon as the truck gets cleaned. Disposal had to be attempted in such a way, place, and time, as to attract zero attention and not get found. Thus the truck would be a logical transportation means - to a swamp, or a landfill, or something like that.
