Starting in January, someone began leaving empty A1 steak sauce bottles around the Avon Lake Public Library in Ohio. In total, employees have found 30 steak sauce bottles that still emit the smell of the famous sauce. The culprit has been leaving these bottles all over the building, on shelves with magazines, books, and newspapers, but the mystery still remains. Employees have even tried finding a pattern in the placement of the bottles, but to no avail.
