Riley

Private Riley was a friend of Private Kappus, and was in the same squad as Kappus, Private Jenkins, Private Bicenti, Private Manuel Mendoza, Corporal Lovik, and Sergeant Johnson.

He barely has any lines in the game, and is only notable for the fact that he is the first person we see successfully attacked by an Infection Form. Though Kappus soon removed it, it is undoubtable that another soon found him.
