My parents have lived right off the Mount Rose Highway, in Galena, for 20 years.
There aren't a lot of reasons that a 19 yr old girl from Reno would be driving up that far on that Highway. That parking lot is for an 'event center' which mostly does weddings, etc. She had no reason to be there.
I think someone was just dumping her car there. Sadly, she might be found eventually, in the remote high desert which surrounds the area.
I was in Reno recently and got lost driving, and in broad daylight, I was surprised at how many obvious drug users, and meth heads, that I saw wandering around the neighborhoods. I am worried that this girl ended up stepping into a bad group of people and paid the ultimate price for it..
