Ron said No cousin, No fight, No gun. Misty is saying there was a cousin who got in a fight with Ron over a gun.
What I am wondering is if Misty is mixing the different incidents together. Her cousin was down staying with relatives because he was the one who had gotten into a fight about a gun that was stolen. Ron found out told him to hit the road. To Ron, there was no fight between him and this guy but he didn't want him around once he found out this guy had stolen gun. To Misty it is all connected.
Going back to the way she told the 'blanket story' she seems to string events from several different time periods into all one making it sound as though everything is connected when it may in fact be not be.
The only other reason I can come up with for Ron's denial about this, other than an outright lie, is that he wanted whomever may have been involved to think that he hadn't spilled anything to LE [or insert one not to be named bounty hunter] yet about it.
I did find the comment 'I have no enemies' interesting. He has said that before also. It is just so hard to tell what is really going on. On one hand if he knows or suspects something I can see him not wanting to say anything because then 'they' would know that LE also knows. If he were hiding things then he also would not want to say anything because it would shed light on it.
Grrr It would help if we could at least know if we have the corner pieces of this puzzle figured out.
