Joseph Brown

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."

Trivia

 * Although the exact date of Joseph's death is unknown, it can be inferred that he died between September 26 (the day the Origami Killer claimed his first victim) and December 20 (the last day of autumn, the season during which the killer strikes) in 2009. If he died outside this time frame, Scott would have no legitimate reason to suspect Gordi of being the Origami Killer.
 * One of Ronan Rouxel's CG renders for Heavy Rain was an unnamed child's head. By process of elimination, this render most likely depicts Joseph Brown: the child is a black male, so it can't be Jeremy Bowles or Jessica (who are white and female, respectively) and almost certainly isn't Reza (whose father is Middle Eastern), and none of the other unseen children in the game are as significant to the plot as Joseph is.
