This isn't the end. With the racketeering charges including murder there's a special thing with proving the murder cases or something.
It's a "Kill 'em all let God sort 'em out" type of thing. They're all guilty of the crimes in which they have been charged. (the "Kill 'em all" part) Now the jury (playing the part of "God") has to sort out who's guilty of which murders. Anthony "Twan" Doyle is the only one who is not up for murder charges in this case.
So at this point, they remain in the MCC on Clark and Van Buren waiting to see where they go from here and for how long.
