I doubt anyone would disagree that as time went on the sheriff might have gathered additional information, such as phone records, receipts, computer files, etc., but those things have been discussed.
But that's NOT the type of additional information that would tell us why, on July 20th, he didn't state that he had ruled out any occurrence within the forest, such as wandered off, drowned in water, or attacked by animals. In fact, on July 20th he stated he had NOT ruled out any of those things. Then there were no more searches . . . . Not by people . . . . Not by dogs . . . . Not by divers . . . . after July 20th, yet he waited until August 2nd to tell us he was ruling out wandered off, drowned in water, or taken by animals. He had no new information from searches between July 20th and August 2nd because there WERE no new searches. It "seems" like he outright lied on July 20th when he said he had NOT ruled out wandered off, drowned in water, or taken by animals. Why would he do that? Was he trying to placate us? Was it because he didn't want to be accused of jumping to judgment?
We also know he had already ruled out an abduction as early as July 13th.
I don't believe I've read another accounting of a person missing in a forest where LE had ruled out every possibility, no matter how unsuccessful the searches had been.
IMO
On the video from August, the Sheriff said "I can't completely rule it out " referring to abduction. BBMAt about 5:34
