I actually said i personally have ruled out the A-Frame haha, i understand that others haven't though that's fine, it's just my opinion. I think the fact that they did a search of the grounds when she went missing and turned up nothing is part of the reason he didn't expect to find anything, also possibly that there's some other suspect or scenario completely unrelated to the A-Frame where they have evidence but not enough to bring charges or at least very strong reason to suspect it. Didn't they search the grounds of all of the houses in the immediate area? Was likely to corroborate the witness testimonies that Maura didn't go to their houses as they were obviously all questioned and said she didn't come to their home.
Sorry I miss read that. Isn't the A frame where they found blood in the closet?
As I recall I don't think Rick would let them search his property. I remember when he moved his trailer they ended up stopping it on the road and searched it then because it was considered some type of vehicle and was not on his property.
