Blueprints for the new Iowa State Penitentiary may have been stolen.
A break in happened last week at the construction site, and some laptops and tools were taken.
Drawings for the new prison were included in the missing software, but no one knows for sure if the thieves knew that.
Shanks have also been found inside a roll of crackers at the prison.
This is in addition to the handcrafted ropes and unknown that was found earlier this week. More on that story here.
