So Scheiderer, BCI special agent in charge of the case, sent a photo of a gun with a silencer on it to GW4 by text message. This is the 22 mentioned in the evidence. It is the type of gun and type of silencer (made with a maglite flashlite) that BCI thinks was used in the murders. 3 guns were used in the murders one at least was a rifle used at Chris Sr's. where ballistic evidence was found on Chris Sr's front porch, living room and under his house.
When GW4 saw the photo of the gun with the silencer he started texting and or calling his family telling them they had a family emergency on their hands. So there was a big flurry of activity going on between the 4 Wagner's and BCI has alot of their conversations recorded and on texts.
