(CBS) — A puppy thief is striking pet stores in the suburbs.

CBS 2’s Roseanne Tellez reports.

The female suspect appears to have struck twice, making off with one puppy in Bolingbrook and one in Naperville. She may not have realized cameras were rolling, CBS 2’s Roseanne Tellez reports.

The blond-haired suspect, in a black and white striped scarf, asked about kennels shortly before the theft. The owner of the Naperville Petland store said she also asked to see a puppy; an employee comes in with little Casper, a 2-month-old Havanese.

Moments later, both would vanish.

Casper could be in trouble because he needs special care.

The Petland staff would learn that just 30 minutes earlier, Hercules — a 3-month-old male Maltese — met the same fate at a Petland store in Bolingbrook.

The woman in the surveillance photos there also is wearing a black and white striped scarf.

Petland is distributing flyers with both images of the suspect and descriptions of the puppies, who have microchips that could identify them for certain.
