FORT PAYNE, Ala. -- A 62-year-old grandmother arrested in a prostitution sting in Fort Payne has begun serving a two month jail sentence.

Last night, a Fort Payne municipal judge sentenced Mary Clark Duncan to 180 days, but suspended all but 60 days of the jail term.

Duncan's daughter, Theresa Duncan, was also arrested August first.

The mother and daughter were arrested Aug. 1, after they allegedly both agreed to have sex with an undercover officer for $30 -- at $15 each.

Fort Payne Police Chief David Walker said the sting was carried out after his office received several tips that the women were engaged in illicit activities.

“Prostitution is not something we see a lot of in the Fort Payne area,” Walker told The Times-Journal. “However, we are glad that something of this nature was brought to our attention, and were able to put an end to this operation.”

There were two men at the home at the time of the arrest, including Teresa Duncan’s estranged husband and Mary Duncan’s son. No charges have been filed against the men, Walker said, according to The Times-Journal.
