Hey, I have just seen a video on CBS and in it a picture of the RJ smile is shown and with it are the pictures of 7 suspects. Now you can't see the faces because they are totally black but from the shape of them you can tell that it are most likely these seven people;

Gale Betram
Ray Haffner
Paul Fricke
Doc Dugan
Vint Molinari
Walter Mashburn
Dean Harken

Now I don't know if these names are actually the names of the final 7 but if they are then it would be very surprising because most of these names with the exception of Betram and Mashburn aren't mentioned very often in any RJ theory.
