NK is charged with
initial charges
18.2-19 accessory after the fact
18.2-323.02 concealment of dead body
additional charge
18.2-18 accessory before the fact
DE is charged with
18.2-47 Abduction by Force, Deprive of Liberty
18.2-32 Murder: 1st Degree
If I remember right there were a couple of news agencies that initially reported that NK's charges were going to be upgrade to Murder in the 1st Degree but they ended up being altered from accessory after the fact to accessory before the fact. I think the Ramirez tweet showing image of charging doc was not accurate - in the tweet just before she got it right and reported accessory before the fact as the new charge. But the image she shows lists the penal code for murder in the 1st which is where I think the confusion comes into play.

I would not be at all surprised to see that charge eventually added though.
