Atlanta Journal Constitution reports that:
Military officials have charged Staff Sgt. Rashad Valmont with murder in the fatal shooting of Master Sgt. Pedro Mercado at Fort Gillem, U.S. Army spokeswoman Maj. Lenora Hutchinson told the AJC on Tuesday.
The report then goes on to say that:
The charge of premeditated murder was recommended Tuesday by the U.S. Army’s criminal investigations command . . .
So apparently the CID investigation is “complete” (for all that means to those experienced in dealing with CID).
