Professor Samuel Bolivar is one of the characters in the game.
He was assistant for Sadie's parents when they were in Peru. Now he is a professor in the University of San Marcos. He organized an exhibit about the Keatings.
He grew up in the Florida panhandle under the name of Jim Monahan. He was chased out of the country, settled in South America, and changed his name. But truth to be told, he stole some of the works from Sadie's parents and nearly killed her father, so they fired him in their time.
