Perhaps no one ever told him it was unwise to return to the scene of the crime. Again and again. Prosecutors say 38-year-old Idris Allen has admitted to robbing the same 7-Eleven store in Newark, NJ, on three occasions over four days in December. Each time, Allen grabbed candy, brandished a knife, then fled, prosecutors say, per NJ.com. A manager was finally able to point him out to police after he returned to the store a second time on Dec. 11, having already robbed it that same day, prosecutors say. Allen pleaded guilty to first-degree armed robbery on Friday and is due to be sentenced on April 24. (More robbery stories.)
