The end of this article sure makes it sound as if JD was aware that FD had some sketchy financial/business doings. I wonder how many people were involved in these doings, and who all knew that JD was aware and looking to expose this. I posted something similar way back, a theory supposing that FD mentioned this exposure to someone who also felt it had to be kept quiet. For sure FD and MT knew that revealing this info to the mystery person/s would put JD in danger. Either they murdered her, or were accomplices to someone else doing the actual deed.
