Mr. Thornsby

Mr. Thornsby is the security guard at the Coolsonian Museum. He suspected Shaggy Rogers and Scooby-Doo of stealing the swords after they were taken because they were in the room at the time. His boss, Mr. Dayton, threatened to fire him if the swords weren't found by the time he left for his vacation. He was a suspect of being the Samurai Ghost, but he was innocent.
