CN....Rita's son. He is the uncle.
He confirmed that George 4 is a glock man and that he (CN) actually helped George buy a 40 caliber glock from someone on Facebook. They drove to meet the seller on the highway -- which in my opinion was probably a highway rest stop -- to buy a 40 glock.
A 40 glock was used in the murders.
CN not only "testified" to George being a glock man, but also that George dyed his hair.
See photo:
Defiance Farms (George 4's hair dyed black)
This photo specifically shows George 4's hair dyed black. Also, a different witness mentioned the dyed hair, a person who left their car with the Wagner's to repair.
Does this matter? Yes. Canepa mentioned the hair dye of George and Jake.
