You did actually steal the goods. Unfortunately for you, they hear this story day in and day out. "I forgot", "It fell in", "Someone put it there" - all are common, and none of them work.
How do you not realize that you're holding a bag of goods?
Sorry, but if a stranger on the Internet doesn't believe you, the courts won't either.
You need an attorney. And yes, this could ruin your career.
