They brought cadaver dogs onto the property and searched the outbuildings as well as the house. I'm sure if there was a scent anywhere of a dead body on that property, the dogs would have picked up on it.
I don't know how many acres the farm is, however. But, I would certainly hope law enforcement was very thorough in their search.
If that was Doug who was crouching behind the four door gray truck across from Venus's parents home around about the time Venus disappeared, I would think he'd want to get out of the area as soon as possible.
What really puzzles me is why he would have been there in the broad daylight where he could have been spotted by someone driving by such as the neighbor!
I don't know how long Venus owned the truck, but if she bought it and was driving it around town before moving to Virginia, I would think Doug would have been really cautious about being seen driving it.
It is so puzzling that Venus disappeared in broad daylight.
