And Wednesday, that's just what happened.
"A Sharpsburg citizen was browsing our Website and spotted Mongan's picture," Mullendore said.
The citizen, who has asked to remain anonymous, recognized Mongan as a twice-a-day customer at the Sharpsburg General Store at 208 S. Church St. in Sharpsburg.
A telephone call to Sharpsburg's resident deputy, John Martin, set the wheels in motion, Mullendore said.
On Wednesday night, Martin posted himself outside the store and took Mongan into custody when he arrived, Mullendore said.
Mongan, of 20132 Hog Maw Road, Keedysville, has been sought for more than a year for failure to pay approximately $11,000 he owes in child support, according to court records.
Friday afternoon, Mongan appeared before Family Law Court Master Daniel Dwyer, who sentenced him to serve 210 days in the Washington County Detention Center for contempt of court and failure to appear, all of which Mongan admitted.
Dwyer recommended work release so Mongan could work to continue to pay for the seven children to whom he owes child support.
Sending a deadbeat dad to jail isn't unprecedented as Washington County Circuit Judge John H. McDowell sentenced another deadbeat dad to three years in prison last October.
In that case, the actual criminal charge that sent Rodney Dwayne Weaver, 36, of Big Pool, to prison was violation of probation in a child support case.
