I have had this experience and have been searching for any explanation, and have now only heard of you in Kentucky, having what sounds to be the same phenomenon. As you have ruled out every possibility, there is no rhyme or reason for the fruit simply vanishing overnight. The fruit was abundant all over the trees, apple trees, and a pear tree, were simply naked. No fruit on the ground, no person or many people could not have occupied our property to strip the trees without us knowing. Nothing is close to the trees for any animal to get into the tree other to climb. Birds only peck at the fruit, they don't fly off with it.
We live in Western Washington (State) on 11 acres, lake front property. All the trees are fairly close to the home within a 50 yard radius visible to us from the home. There is no answer from what I'm finding. I do believe there are many daunting, teasing, taunting, persistent, and ever-present spirits that are dwell on this property, unknowing if this was an American Indian burial ground or something else that may have happened here, but it wouldn't be surprising if this is a haunting of some sort. I have gone as far as smudging, blessing. and praying over this home and property close to the house itself, not the parameter of the 11 acres. We've got so many other things that are much more harmful and violent that have happened to us, though the missing fruit is something I feel may help me get some sort of logic to work with.
Still seeking answers.
