Credit cards taken from the wallet were used at several locations in the Grand Haven and Muskegon areas, said Sgt. Bruce Morningstar of the Fruitport Township Police.
The victim told police she had been shopping at the Meijer store, 5300 S. Harvey St. The woman said she later realized her wallet was missing from her purse, which had been sitting in the child seat portion of a shopping cart.
Police are working with the retail establishments where the credit cards were used in an effort to identify a suspect.
No further information was released.
