BILLERICA (CBS) – Police in Billerica are trying to identify a thief who stole from a Hallmark Paper Store.

Officers say the woman walked in and went right to office in the rear of the store.

Surveillance video shows the woman trying to break into the store’s safe. When that doesn’t work, she rummages through a worker’s purse and steals her wallet.

The suspect is believed to be in her early twenties, 5’2”, 115 lbs, with long brown hair. She was wearing blue jeans, a purple shirt, and black shoes.
