They are in a home these days.
Thank you for posting that. The photographer, Roger Ballen, is cleary a poor artist who attempts to conceal his lack of skill by betraying and exploiting his subjects.
The article says that they drooled uncontrollably, which probably explains the stains on the shirt.
The other thing is the author keeps mentioning them in past tense: "Casie and Driesie, the twins, were mutes, with the mental capacity of five-year-olds, according to a psychiatric assessment record."
He does this several times throughout the article. It makes me wonder if they're still alive or not. Interesting, though.
