Mr. Carswell was a bank president.
Mr. Carswell is a slightly overweight and out of shape middle-aged man with white hair. He wears a blue suit, white shirt, and a black tie, along with glasses.
He acted friendly and well-mannered, but in reality, he is an embezzler who violently beats up one of his own bank guards who had evidence against him.

They brought him to Carswell's house. Once the gang had left for the barn dance, Carswell then proceeded to tie up the bank guard and lock him in the basement; then went after Scooby-Doo and the gang when he realized they held the evidence (they innocently took from the bank guard) that proved he was embezzling money from the bank.
Mr. Carswell: Blasted meddling kids!
