Shirley Bodell is accused of three armed robberies in all, all "Check-and-Go" stores.
She was charged Wednesday for a robbery that happened last Friday evening in Charlotte.
Police say she's responsibility for one in Hastings just an hour before, and another last month in Kalamazoo.
Sixty-two-year-old Shirley Bodell worked at "Check-and-Go" in Battle Creek until this fall.
Police say in each of these robberies, she entered the store with a handgun. She took cash, and then took the clerks to the back of the store where she told them to lay down and count to 100 while she made her getaway.
Even just one conviction could mean life in prison.
