A Weston woman who police said orchestrated a refunding scam at Marshall's and TJ Maxx is facing charges after turning herself in at Fairfield police headquarters last Thursday.

Kyrstyna Gibek, 60, of Tubbs Spring Drive, was charged with fourth-degree larceny and possession of a shoplifting device following an investigation that was begun in October 2011.

Store employees identified Gibek as the person who would buy high-priced merchandise with cash or a store value card from one location, and then attach the tags to lower-priced merchandise she had bought at Marshall's or TJ Maxx outlets, according to the report. After switching the tags and merchandise, Gibek would go to another Marshall's or TJ Maxx store to return those items for the higher price while keeping the original higher-priced merchandise, police said.

She allegedly made 439 refunds and cash returns totaling $70,000 from May 2009 to present, police said.

Police executed a search-and-seizure warrant at Gibek's home on Nov. 19, seizing assorted price tags, store receipts, sewing kits and supplies and manufacturer's labels, as well as clothing where those labels had been poorly sewn into sweaters and shirt collars, police said.

Gibek was held on a $10,000 bond and is scheduled to appear Jan. 4 in Bridgeport Superior Court.
