EDIT:
Here is the actual text exchange as read in court by Ms. Dugan. Recall that at this time, per Charlie's testimony, he already knew the details of the murder and the supposed extortion, which he relayed to Donna.
8/2016 Text Exchange Between Charlie Adelson and Donna Adelson
Charlie: Did you see in the paper where State’s star witness that rented the hotel room is a convicted cocaine dealer? Maybe those guys were just up in Tallahassee buying drugs and just in the wrong place at the wrong time. Maybe the coke dealer did it because Danny didn’t pay for his drugs just like he stiffed everybody else he did business with. This whole thing is just crazy.
Donna: I didn’t see. Which paper?
Charlie: Tallahassee Democrat
Donna: Wow, I’ve stopped reading everything.
Charlie: The guy admitted to selling cocaine and hanging out with them.
Donna: OMG!
