Joseph Brown was a child who was killed with the modus operandi of the Origami Killer. He was last seen getting into Gordi Kramer's limo, and was found dead several days later, with drowning as the cause of death. It is this incident that causes Gordi to become the prime suspect in Scott Shelby's investigation into the true identity of the serial killer. Gordi kidnapped Joseph as a copycat act of the Origami Killer. Charles Kramer reveals in "Face to Face" that Gordi held Joseph under the water for too long and cried after the boy died, but also downplays the severity of his son's actions by insisting that no one will miss Joseph because he was "just street trash like so many others."
