The description at imgur said, “A family went to movie for 3 hrs come back to this.” Whoever left these prints apparently found a stock of ink and had a grand old time.
The evidence leads through the home. Who could have committed such a crime?
The perpetrator didn’t get in the bed, but he obviously thought about it.
I believe we have found the guilty party. The good news is that the floor was fairly simple to clean, and the ink was non-toxic. The bedspread will be a permanent reminder to put the ink away where unauthorized users cannot get to it. There are 11 pictures of the carnage in the imgur gallery.
