mystery solved!

Remember this? Well, I caught the children leaving their clothes just now! Here's what happened--I was going downstairs a few minutes ago and happened to glance out the east window. That's when I saw a person running across the eastern fence of our property. So I went downstairs and outside to look in that direction and there were three children leaving their clothes and shoes at the corner. So, I yelled at them "hey. take your clothes and go leave them somewhere else. this is private property". They picked up their belongings and left.
