Pedeaston was the host of "The Wild Traveler" radio show in GTA: San Andreas -- in which he openly recounted acts of pedophilia -- and, in GTA IV, he was "arrested by the Indonesian police after being suspected of child molesting in Bali, Indonesia," according to the GTA Wiki. The casting call describes Pedeaston as a "man-boy love activist who just got released from an Indonesian prison," suggesting that the role would be set in a time period following the events of GTA IV -- in other words, a role featured in the next GTA game.
Additional first-name-only characters are listed in the job posting and sound generally befitting of a GTA game -- take "Samantha," for instance: "A young female obsessed with sex parties, always dreaming of being a Hollywood celebrity." The Actors Pages casting call follows a similar job posting on The Agency, for a project named "Rush" (assumed to be a codename and linked to Take-Two), which introduces more puzzle pieces that might fit together into a new GTA game set in Los Angeles -- or "Los Santos," as it's known in San Andreas.
