CARTERSVILLE, GA -- It was a story that made a lot of people mad. A woman posed as a representative of the charity Toys for Tots and tried to collect money from several businesses. There's good news. Police know who she is thanks to the suspicions of some of her victims.

Marsha Lynn Foster, age 47 of Decatur, is charged with two counts of Theft by Deception and two counts of Identity Fraud. Cartersville police have warrants for her arrest.

Maribel Cruz, an assistant manager at Servicios Supermercado, a Mexican grocery store in Cartersville, helped police identify Foster. "I feel like really happy because we stopped her and if we hadn't called police I don't know how many other people would have fallen for it," Cruz said.

Cruz says Foster came into the store Wednesday and handed her a business card she said was hers. But the card was Tara Friedman's, a manager at Stars and Strikes, a family entertainment center in Dacula. Friedman says Foster tried to solicit a donation from her last Friday. Cruz says she gave the woman $100.

At Barbarito's restaurant in Winder, manager Josh Armstead said the same woman solicited $50 from the business using Tara Friedman's business card. Armstead said the woman claimed to be working for Toys for Tots.

On Wednesday, the same day Foster scammed Servicios, she also went to Brandi's World Famous Hot Dog stand in Cartersville. Brandi's gave her $100 for Toys for Tots.

After leaving both Cartersville businesses with the donations, both Cruz and a manager at Brandi's became suspicious. "I don't know, I felt something weird about her," Cruz said. She took down the license tag of the car foster was driving. She also made a note of its make, color and body style. She called the number on the business card Foster gave her and found out it wasn't the woman she met.

Cruz called Cartersville police who traced the tag number to a rental car company. The company told police that Marsha Foster rented the car under her real name. That's when police took out the warrants.

Cartersville police Captain Frank Cline said these types of scams are very common around the holiday season. He says people need to choose their charities wisely. "You don't ever want to donate to somebody going door to door unless you're totally aware of their identity," he said.

Cruz says she learned the hard way but it was only out of the goodness of her heart. She remembered what Foster told her when she left the store. "She said God bless you," Cruz said. "That's wrong, really wrong using God's name."

The businesses that were victimized were in Barrow county and Bartow county, counties that are on either side of the metro Atlanta area. Police wonder how many people have been victimized by Foster that they haven't heard from.

According to the Georgia Department of Corrections website Foster has a history of convictions for Fraud, Theft and Forgery. In 1993 she was sentenced to serve two years in prison for First Degree Forgery. In 1999 she was convicted of First Degree Forgery, Fraud and Theft by Taking and sentenced to serve two years. And in 2001, she was convicted of First Degree Forgery and Fraud and sentenced to serve five years in prison.
