What does the store owner need to prove in order to convict Kevin of shoplifting?

To successfully convict Kevin of shoplifting, the store owner needs to demonstrate that Kevin willfully took possession of the items without the intent to pay. This notion encompasses both the act of taking the items and the mental state associated with that act. Shoplifting typically involves the wrongful intention to permanently deprive the owner of the goods without compensating them, which is fundamentally established by showing that the individual had the intent to take the items without intent to pay.

While leaving the store without paying is indicative of theft, it is not sufficient on its own because it doesn't necessarily establish the intent behind the action. Moreover, express intentions to pay for the items later or claims of unawareness may provide defenses that weaken the shoplifting charge, as they demonstrate a lack of intent to commit theft. Thus, establishing the willful possession coupled with the absence of intent to pay directly supports the case for shoplifting.
