A Winchester woman has been charged with fraud after faking cancer in a scheme to steal nearly a million dollars, federal prosecutors said.

Sager Kopchak, also known as Sager Dallai, 34, has agreed to plead guilty to four counts of bank fraud, Acting U.S. Attorney William D. Weinreb said.

Kopchak stole nearly $1 million forging checks and using routing numbers from stolen checks, buying 2.05-karat diamond earrings, five fur coats, Chanel purses, a Cartier watch and a trip to the Bahamas, federal prosecutors said in a statement. According to court documents, in late 2009, Kopchak contacted a person she knew asking to stay with that person while she received cancer treatment.

“Kopchak did not have have cancer and was not undergoing cancer treatment,” prosecutors said, adding that while in that home she stole a checkbook she used to make purchases.
