Did the Laundrie's know the area Brian would normally go in the reserve - Yes, according to CL. Did CL go to the same area to assist in the search - Yes. Has the water level dropped since CL was last there - Yes. Was the area opened up to the public yesterday - Yes. Have people been asking why they haven't made more of an effort to search for their son - Yes. Did they go searching for their son the first chance they got - Yes. Did the Laundries plan an elaborate escape for Brian and hole him up somewhere nice and cosy? - Doesn't appear so for the fact that as soon as they got the chance to search in the reserve, they did. Suggests a strong belief they knew where in the reserve he liked to go hiking. Did Brian die yesterday/this morning - Doesn't seem likely if there were only partial remains found. Bearing all that in mind, especially the last part. Of what benefit does it serve his parents to find evidence near "his" partial remains?
