A Douglas County Superior Court judge has sentenced a Fayetteville husband and wife to 20 years in prison for the 2007 armed robbery of a Lithia Springs dollar store.

Preston Marcelus Calhoun and his wife, Rosylnn Ford-Calhoun, both 42, were sentenced Monday by Judge Robert J. James after entering guilty pleas to one count each of armed robbery, according to Andrew Agan, spokesman for the Douglas County District Attorney David McDade.

The two robbed the Dollar General Store in Lithia Springs at gunpoint on Sept. 10, 2007, and were arrested three months later after a chase in Henry County. They were fleeing an attempted robbery at a Cato’s clothing store in Henry County when they were captured, Agan said.

A Henry County jury has already convicted the Calhouns of two separate armed robberies.

Agan said they have been tied to a dozen robberies across metro Atlanta and are awaiting pending charges in other jurisdictions.
