Justin was a Glader who's name was seen engraved on the wall of the Glade in The Maze Runner film. His name was crossed out at the time, therefore he was dead when Thomas arrived. It is unknown what he looks like and is never mentioned. The cause of Justin's death is unknown, however it is presumed for him to either have died from a Griever, in the Maze if he was Banished after being Stung and gone through the Changing, or perhaps to have been trapped and died in the Maze if he was one of the first Gladers. Based on the types of possible deaths, it is presumed for him to have been a Runner.
