Yes, a short update would be just fine. Something brief would be enough, such as: "XX has been arrested for the murder of Missy Bevers. The murder weapon was XX, the body was found in XX, and the cause of death was XX."
Just give us that much and we'll go from there.
Shoot I will settle with a person of interest or even the actual COD so we can profile a bit. Or goodness how about an FBI enhanced photo of the he/she or even a definitive statement on the sex of the perp. Any of those items would help cut down speculation by a 1/3. And a statement that it was dogs blood so we can bury the shirtgate theory. Lol [emoji12]
