I saw on a YouTube video a trick to see if someone messes with your stuff in prison. You put some baby powder in your hand and blow a fine dust over the item. If it was moved you can see it in the dust. Almost like if you take an item off a shelf to dust that hasn’t moved in a long time there is a mark on the shelf where the item sat and dust couldn’t get underneath. So if it’s a candle for example you’ll see a circle on the shelf where it sat. If it doesn’t line up perfectly you know it was moved.
