This is what Alexander, the "lead detective" on the case from CC has to say about that:

There have been similar reports elsewhere that no CP was found at BD's home. Also, if it had been, it would have been mentioned in the afidavit for sure, and it wasn't.
The original reports quoting the sheriff as saying that there was were either misquoting him (and subsequent reports simply repeating the misquote in other contexts to make it look like new quotes) or he was delibrately trying to pervert justice. Repackaging old news of dubious accuracy commonly passes for journalism these days, so it is possible that is what happened. But whatever the case there isnt any doubt that there was no CP in BD's house.
If the sheriff really did say that when he knew it wasn't true then he is probably liable for civil damages.
