IMO, here's a few things that CL may have going for him in his favor from a defense point of view; all are JMO only. However, I do NOT for one minute believe he was innocent and I DO believe NL was involved either before, during and/or after, and I believe there MAY be a possibility she is more responsible than he is.
1) Tire tracks from their vehicle at site where Erin's car was found. Does this prove who was driving Lee's vehicle?
2) Rebar and 22 caliber casings found in mine and match those found in their vehicle, which both Lees would have had access to their own vehicle and things in it. (Of course we don't know what LE has regarding fingerprints etc)
3) 22 caliber rifle at the “ranch” that was in their home previously. Who put it there, NL or CL? If it was in the Lee's home or at the ranch, both of them would have had access to it.
4) I am not sure if we KNOW if it was text messages and/or actual phone calls from Erin to her friend in TN regarding going out to celebrate with CL, but irregardless, IF CL and Erin were supposedly in contact with each other (possibly) per text messages regarding this day to celebrate, who's to say that NL wasn't sending the texts to Erin on behalf of CL (using CL's phone)?
5) Regarding internet searches for how to dispose of a body – both NL and CL (I'd assume) had access to the same computer that was used for this (assuming it was a computer in their home).
And yes I do realize, CL allegedly also asked someone how to dispose of a body as well.
6) Who typically would have been the most upset about the alleged affair between Erin and CL? NL or CL?
Regarding the red car sighting, I am still not convinced of this. I am not saying MB is not a reliable witness, nor am I saying he did not see what he says he did, however, we all know witness testimony can a lot of times not be correct etc. I would think we would have heard more about this red car somewhere along the line but I guess only time will tell. I do find it interesting that the Lees' Jeep is maroon, but I would think the general public would know the difference between a maroon/red Jeep SUV versus a small red car. One scenario I can say that could play out is CL and Erin met that morning of June 28 somewhere near JTNP; the only reason I feel this is possibly where they met is because she had allegedly told her husband she was going to JTNP (although for different reasons regarding her mother's visit, etc) AND CL had allegedly said he was going “hunting” at JTNP. So then either CL or NL or both take Erin to the mine (enough said there) and then someone drives Erin's car back to where it was found and has someone pick them up, and this is where the witness account of MB comes in. And IF it's possible a maroon/red Jeep SUV is mistaken for a small red car, it could be possible that Erin left her car where it was found and CL picked her up there for their day together and this is what the witness allegedly saw.
