Scooby-Doo, Where Are You!
When the gang found a bank guard out in the middle of the road, in a half conscience state, they took him to his boss's house after finding the address of the latter's in the wreckage. Once there, Mr. Carswell had him laid on the couch with a blanket over him, promising to take of him. In reality, Mr. Carswell took him down to the basement because the bank guard had incriminating evidence against him that revealed he was stealing from his own bank. As the Creeper, Mr. Carswell made it look like the guard had been in a car accident from a falling tree, but he had really set up a trap for the guard so he could ransack him and the inside of his car to find the evidence against him.
By the time the gang caught Mr. Carswell as the Creeper, the sheriff had freed the guard.
