A Chicago Bears signed helmet, destined as an auction item for the Dixon Schools’ Stupor Bowl, was pilfered during delivery of the item. (Alex T. Paschal)Just nine days before it was to hit the auction block at this year’s Stupor Bowl in Dixon, police are searching for a signed Chicago Bears helmet that has gone missing and is presumed to have been stolen. Dixon police on Thursday were continuing their search for the culprit who may have stolen the Chicago Bears replica helmet signed by player Cole Kmet. However, the bus company staff didn’t recognize the name on the box and rejected the package, Wadsworth said. Inside was the branded helmet box, but no helmet, Wadsworth said.
