Humm is right... just guessing here (MOO), but my money is on the MM being one of the other POI's back when LE was stating there were "several".
3rd year law, wonder if he graduated with the rest of the class? Wonder what the "relationships" were like between the 3 of them (MM, SM, LG)??
Still more questions than answers.
I feel like LE has pretty much ruled the MM out at this point, but when you go back to all the "rumors" there was always the one that "rumored" SM was just a pawn to flush out the "real" killer... don't really buy that thought though, does not make sense why anyone would allow themselves to be used that way.
Puts the "termination" talk into a new light though and makes it sound as if the MM was only serving out his notice to leave the job.
