I hope there is a good outcome for this little one. It is not looking good though.
Ironic for me because Deorr Kunz Jr., also age 2, disappeared in Idaho almost eight years to the day as Emile. That means nothing except as a sad coincidence in my reading. In his case, parents were named suspects.
This case has made me think about other cases where little ones do genuinely wander off, if that's the case. I think one of the most dangerous times is when you have a family gathering or a lot of adults around. It's assumed that someone will be watching the child because there are so many people around. "I thought you were watching them." You must always designate who is watching the kids, then specifically hand off to someone else if you are not going to continue to supervise. It's tempting to not do this, because it's such a nice feeling to think, "We're all here together taking care of our children." But little ones, especially two year olds, don't act that way. You do have to keep an eye on them every second.
It sounds like this was an area where people felt safe to let their kid wander, assuming that everyone else was safe.
Two year olds are different. You cannot do free range parenting with them (or even older kids up to a certain age.)
I don't know if that's what happened here. I just know that there is case after case where adults assumed that the child was being supervised by someone else.
