(IDAHO FALLS, ID) — Idaho Falls Police say a man who robbed a Maverik station earlier this month was the clerk’s own son. 18-year-old Mark Carroll walked into the store on New Year’s Day and demanded money from his mother, Donna Carroll. The suspect was arrested last week on felony armed robbery charges, though he was already in jail on an unrelated charge. Still, the woman says she doesn’t believe it was her son behind the mask and gun. Officials emphasized that has not been implicated in the crime.
