There's some photos on this FBI page of a 17 year old kid, who was fingered by our internet detectives - and has already come forward to clear his name
These are pretty clearly different people than the 17 year old. The Yahoo article is currently confusing cause it has photos of the actual two suspects and none of the person who came forward on the story, but the person who came forward isn't in the FBI photos.
