A well, a drainage ditch, a field that was plowed, a construction dumpster...He had to choose a place that was not readily seen from the road between 8 and 10am.
Or DS lied to RS and actually dumped her in his original spot.
We have to consider that even though Doug thought he could get away with murdering Venus, he had to consider that Ricky Spencer might talk.
Doug Stewart may have convinced himself that even if Ricky Spencer talked, if he had no clue where Venus's body might be, he could be portrayed as a crazy liar.
Where Doug messed up was by leaving the Walmart receipt in his truck, the tarp cover at the murder scene and tire impressions in the field.
Had there been no Walmart receipt or tarp cover and the person didn't see and report the truck, what would the police have to go on?
Doug was convinced having Ricky Spencer pose as him would work. However, he had to cover his bases as well so lying to Ricky would have been the perfect plan to throw the police off as to how far from the murder scene Venus's body was buried.
Doug may have convinced himself that there was no way he could be charged with murder without Venus's body being found. Besides making sure he wasn't caught at or near the scene of the abduction, Doug's main focus had to be making sure Venus body is NEVER found.
To eliminate that possibility, Doug could have intentionally fed Ricky Spencer inaccurate information.
If Doug did bury Venus on his father's property, that would have added 20 minutes driving time to the trip for driving in the opposite direction he needed to travel to get back home.
If Doug was planning on burying Venus on his father's farm, surely he would not have let Ricky Spencer know that.
Surely Doug discussed his plan to murder Venus, including the particulars, with his father who could have said, "If you are going to bury her here, you can't tell Ricky that! You need to make him think her body is somewhere else! This is what you can do! After you've driven for a couple hours, call him and tell him you are near the grave and you can't put her there because there are people there then wait an hour or so and call him back and say you're done. That will convince him she's nowhere near Colon. If he goes to the police, or tells someone this story and they go to the police, everyone will think she's buried two hours drive away from where we've put her here on the farm! They'll NEVER think that you were lying to Ricky!"
