Officials say in October a 61-year-old woman reported her wallet stolen. She told police that one of her credit cards was used at K-Mart.
K-Mart video surveillance shows one of the suspects use the woman's credit card to purchase several gift cards.
Police say, shortly after, both suspects re-entered the store and used the gift cards to purchase electronic items that were worth $500.
Both of the suspects are described as black men, with a mustache, and heavy build.
