Stephen King made two purchases. He purchased his neighbor Natalie's antique typewriter and he also purchased a new computer from Best Buy. Natalie's typewriter had been purchased on credit from Jack's antiques. Natalie had financed the purchase with Jack's and signed a promissory note and a security agreement covering the purchase. The creditor, Jack's, did not file a financial statement, relying on the concept of automatic perfection for purchase money security interests in consumer goods. King was unaware of the history of the typewriter. The computer was subject to a security interest in favor of Sychrony Bank, which had perfected it's security interest by filing. King knew about his security interest when he purchased the computer from Best Buy.

Natalie and Best Buy never paid their secured creditors. These creditors now seek to repossess the collateral from King. Who wins and why?
