Thanks to those who replied to my question. It just seemed odd that LE said that it was probably an elk or something, like it wasn't a big deal.
Granted, because they knew they would not be able to get into the lake at that time, and didn't want to panic anyone, they downplayed the importance of it, but when Wendy took her dogs in and they alerted on pretty much the same areas, I had to wonder why LE didn't think it was much to start with.
Several good thoughts have come up though. Indian Burial grounds. I would never have thought of that, but it's possible. Centuries before we set foot in the area, Native Americans have lived there. We've all heard countless times where contruction is going up someplace and burial grounds were found. Heck, a couple of years ago over by where I live, a business was relandscaping the front of their business and found ancient burial grounds of an indigenous tribe that lived in the area a few hundred years back.
And of course, we don't know if someone else drowned in that lake and the remains were never recovered, this could be why the dogs alerted on the area.
It's just that I like to take LE's statements as the most reliable, over MSM, and the family, because MSM goes for sensationalism and the family tends to be biased in their opinions. IMO
Even at that, LE has been known to leak false or partial information in order to get a specific response, sort of like a fishing expedition. IMO, JMO, MOO.
