BTW, here's one tip related to the concrete residue (which the affidavit wrongly refers to as "cement splashes", since Quikrete is technically concrete, not cement). The affidavit points out these splashes/residues were found "in the rear passenger compartment". IMO, this suggests Brad likely returned to the passenger side door of his black pickup truck AFTER having mixed and poured the concrete. Along with the fact that he drove and likely parked on the right side of the road, this suggests that Suzanne's body is, for both of these reasons, likely located on the RHS of a nearby road.
Say, for example, if Brad turned north on to Peaceful Valley Rd from TX-16 and then stopped his truck on the right-hand shoulder (say just short of that 1-lane bridge over the Medina River as visible in Google StreetView), then he is more likely to have done the burial on the right side of that road. But this same logic works no matter what road he used, just before parking the truck (TX-16, Highland Dr, Peaceful Valley Rd, etc.). In all cases, it's more likely that he would pull to the RHS (to be aligned with traffic when he parked) and it is also consistent with that idea, that the spent Quikrete bag and/or dirty Home Depot bucket went back into the truck on the passenger side, so he never needed to cross the road and potentially be seen carrying these suspicious items. In summary, it means on roads going to the west (like a lot of TX-16), more searching should be done on the north side of the road. Similarly, it means on roads going to the north (like a lot of Peaceful Valley Rd, for example), more searching should be done on the east side of the road.
