BBM I agree with the Sheriff believes the creek has been thoroughly searched. The creek is just not as deep, fast moving and filled with nooks and crannies as some people seem to believe. I have spoken to a few people who have been to the campground since Deorr went missing and there have been some times over the past three months when the creek has slowed to not much more than a trickle.
I agree that little Deorr falling in the creek is the most logical explanation for his disappearance, however, the officials are sure his little body is not in that creek.
While there have not been any organized searches recently, the family, friends and various small groups of caring non-related people have continued to search the area. There have also been local LE, the forest service and FBI personal at the site on several occasions. Pretty much every week somebody has been there looking.
Just for clarification purposes, there is no boat dock at the reservoir. There is a "hand launch for non-motorized boating". The campground is "light" usage, meaning that there are not many people that use it for camping.
