I believe May 17 was when SL went to the media with the story that he gave LE the info on DM last year, from what I can tell, which would be why they suddenly took more interest in LB and WM's deaths on that date. I found it odd that he waited a week, but that is just my opinion. That is not a criticism of him, I just find it odd, like many aspects of this case that others seem so sure of.
I still find it odd that HPS would not have informed TPS that if they were looking for another body on the property, that they might want to look under the hay or in some of the barrels. If Hamilton still had authority to search the farm until the 20th, I find it odd that they either didn't see 54 barrels and have the same suspicions many here had, (that they would be a great place to hide a body or evidence), or wonder what might be hidden beneath the hay. At least one of the 100+ LE involved must have had the same thoughts, in my opinion.
I understand some saying that their warrants might not have covered barrels or the barn specifically, but I imagine that in other cases, when something suspicious is found during an investigation outside of what is currently written on a warrant, that they would perhaps have an officer guard it until they could return with another warrant. I am not suggesting, as I have read recently, that this may be a criticism of LE, but wondering at their reasoning for not looking into large barrels or under copious amounts of hay when conducting a homicide investigation. I imagine that they must have had a reason, I just can't imagine what that would be.
