Fred is a character in DEXTER. Fred is the last unfortunate victim of Brian Moser, the Ice Truck Killer and lost his life so that Brian could have "a set of wheels". While Brian was taking Debra Morgan to the Moser Family House, he met with a man and hit him over the head with some sort of object that left him for dead. He is then thrown into the trunk of his car along with Debra, who continues to scream as the tape around her mouth comes loose. Brian stops the car, steps out and quotes the following:
"Sorry, but you're drowning out Fred's radio and he was kind enough to lend us his wheels."
Fred is never mentioned again, it is likely his body was found inside of his vehicle at the Moser household.
