I've been wondering all along....do ya'll think the purse actually has any significance? People have posted here that they leave their purses in the car all the time. I don't because I'm paranoid and tend to forget where I put stuff, too, so I keep it with me.
The only actual significance I can see is this:
The purse, and her cell phone, were found in the SUV, Nancy's car. BC had been using his sedan for all his trips. The phone call he says NC made was actually from her cell phone to his cell phone, and he made the call himself, and he had her cell in the sedan with him. He then put the cell with her purse in the car to deflect any suspicion about the call away from himself. The purse may or may not have already been in her car, although JA seemed to have been alarmed to have seen it there. Alarmed enough to mention it in the 911 call.
And IMHO, an LV is a purse that suits all but the dressiest occasions. If you have an LV, you probably aren't going to be 'changing it out'. (And even if it had no valuables in it, I still wouldn't leave an LV in the car - it's a valuable all by itself.
