Only other hypothetical scenario I can think of but it's far fetched and way out there is ,Yet, she entered his car willingly. My guess is she thought it was a legit "romantic" hookup or a consensual non-romantic hook-up. I can't see any other scenario at this point. Of course, it ended up non-consensual, and she wasn't able to get away.
I don't think it was volunteer work associated with her job.

Perp stated he was to meet an ex at the club but didn't if it was a true statement, could Decara be either the ex girlfriend ( highly unlikely) or friend of ex girlfriend

I still feel getting into a vehicle of what seems to be a stranger atm although I do feel there is a connection, given the hour it is given vibes of sex work , drug dealing or promise of bringing somewhere innocent like to a friend or younger love interest . Prehaps decara went to the club near closing time to see if she could see a current or ex - beau . Could there have been a hook up between the two exs if they existed? As I said far out there and currently lost in space
