… snipped by me… Usually there aren't traffic cameras in neighborhoods at stop signs, you only get them at big high traffic intersections. Perhaps our perp was avoiding being caught on camera. To dump her in a dumpster behind a business would risk being seen by surveillance cameras. If the perp took her far away S/he would have been missed from being gone too long, AND driven through multiple intersections with cameras.
Didn't we discuss up-thread somewhere that the place in the street where she was dumped was blocked from view from most of the houses? Or at least the passenger's side of the car was facing into a fence I believe. It may have been more private than we think.
This may be graphic, (I never know what's graphic to some, because I'm not squeamish) if you load her into the tarp and into the car inside a garage, then you could prop her on the floor of the vehicle, leaning against the door, so that her weight would slide out onto the curb when you stop at the stop sign and quickly open the passenger door and slide her out. 1, 2, 3, done. I think you could do that very quickly. She was at a STOP sign wasn't she? Goin back to double check.
