Cheryl Patton-Lynch, 46, of Turkey Hill Road, Chester, was charged on a warrant Thursday by Fairfield police for forging prescriptions for Vicodin.

Police said an investigation began in April when a pharmacist at Super Stop & Shop, 1160 Kings Highway, became suspicious about a prescription she had filled. In July, Patton-Lynch was arrested in Old Saybrook because of a forged prescription and police learned she was also charged in Wallingford and Middletown on similar charges. According to police, she used the same doctor's name for the different prescriptions.

She was served with the Fairfield warrant when she appeared in Middletown Superior Court.

Patton-Lynch was charged with illegally obtaining prescription drugs, identity theft and criminal impersonation and released on a promise to appear Nov. 29 in Bridgeport Superior Court.
