WILLISTON, Fla. » A would-be robber picked the wrong time to steal a jar of money from the counter of a north Florida convenience store.

Williston Police Chief Dennis Strow says 27-year-old Michael Wayne Aurilio took the jar containing $35.78 from the Kangaroo store Wednesday. But he didn’t realize an off-duty Marion County Sheriff’s deputy was standing behind him.

The Gainesville Sun reports that as Sgt. William Dietrich tried to take Aurilio into custody, the two fell through a plate glass door. Meanwhile, Williston police officers arrived and took the man into custody. Aurilio and Dietrich were treated at the scene for minor injuries.

The money was intended for a charity that sponsors recreational events for terminally ill children.

Aurilio was charged with robbery and felony battery on a law enforcement officer.
