(Corvallis, OR) -- Sentencing is scheduled for March for a California woman who pleaded guilty to running a complex credit card fraud scheme in Oregon. Federal prosecutors say Mariam Gevorkova led a group of people using fraudulent credit cards to buy luxury items and lavish vacations, who then told the credit card companies the purchases weren't authorized. Losses totaled one-and-a-half-million dollars. Gevorkova also ran two illegal marijuana grow operations and a state-licensed retail marijuana shop in Corvallis, Oregon to sell the pot. She faces a possible 30 years in prison.
