Police say they caught a scammer at the scene of a crime. Chief Brad Hill says John Caudill is suspected of several home improvement scams. Caudill has a criminal record, including previous convictions for home improvement fraud against the elderly. Police say he would show up at a victim's house in a truck with a ladder, climb up on the roof, claim he made repairs and demand payment. They arrested him Thursday at a person's home who believed she was being scammed.
