Emery S. Pluff, 59, of South St. Paul, Minn. , was arrested in February for allegedly robbing and molesting his wife (which he did, police said, pretending he was a stranger). For reasons not yet apparent, Pluff allegedly faked going to work on the morning of Jan. 30 and instead donned a black cape and a Halloween mask the family kept in the garage and entered the house, where he surprised his wife and dragged her into a back room. She apparently was not the least bit puzzled by her perpetrator's identity and asked Emery repeatedly why he was doing this. According to police, Emery replied, "I'm not Emery. " Police said Emery then took some money from his wife and fled, winding up at work, where he was arrested. [St. Paul Pioneer Press, 2-8-01]
