ST. PETERS, Mo. (KSDK) - The St. Peters Police Department is looking for two men and one woman who are suspected of passing counterfeit bills at several Walgreens stores.

St. Peters police said they received calls from two Walgreens stores about counterfeit $100 bills being used at their stores on January 4.

The suspects are described as a black male with short black hair and a beard, between 5'4" and 6' tall and around the age of 30 to 40 years of age; a black male between 5'6" and 5'9" and around 40 to 50 years of age; and a white female between 5'4" and 5'6" and 30 to 40 years of age.

The suspects are said to be driving a red Dodge Stratus and an older model blue pickup truck.

Police say the suspects would purchase items at Walgreens using the counterfeit bills and then later would return the items for cash back.
