I think CN and MB took care of the gun. CN because she is in on the LB murder. MB because she was trying to protect her son. They did it right after they wiped the fingerprints off the trailer. We know that CN called up MS that night, asking questions. She asked him about the gun. He still had it. The press was starting to get on the story. MS told us that a reporter had called house. CN and MB whipped over there and got it and took care of it. CN wasn't leaving the gun in the hands of MS, that would have been too risky. And with the press converging everywhere, it had to be taken care of immediately.
Notice how the Crown hasn't entered into evidence the location of CN's phone after the "little mission" night ? Why aren't they telling us where CN and MB were on the night that they cleaned up the finger prints ? Do you think that is all they cleaned up ? I doubt it.
Every time that CN wants to cover something up she is either stoned, super tired, drinking or having sex. What did CN say her and MB were doing after cleaning up the finger prints ? Drinking copious amounts of wine. Think that was the case ? Nope. They were covering up other evidence - the gun.
