Possibility of Being Tracked down for Shoplifting?

Most stores loss prevention departments only store video between one to thee months. He can probably stop worrying but that does not mean he is not in the stores watch list. This is a list of customers suspected of theft which is kept by the teller. However, the more time that passes the more likely he may have circulated out. If something does come of it, it would be a good option to contact me for legal advise.
