I cannot opine.
I'm lost for words to be honest

I guess emotions run high.
The locals are genuinely worried no doubt.
By the way,
in my earlier link, Police suggested unused mineshafts and wells.
But it is a private property, right?
So...
I would assume that every inch of it was checked previously of such dangers.
That people living there, the owners, were/are aware of them and addressed these issues,
eliminating/securing them, right?
I mean
everyone wants their property to be safe,
especially if there are young kids on the premises.
