Any chance the blood in the car (assuming that’s what it is) could be from the accident that caused the damage? Maybe just wishful thinking. The carjacking theory seems to fit, but I don’t totally understand the strategy behind jumping out of the backseat and scaring someone who’s flying down I-85. Seems like a good way to get in a nasty accident that leaves everyone injured and the (unrestrained) perpetrator too injured to leave the scene and then caught.
Also, two things about the Snapchat messages seem weird to me. First, if you just met someone, you don’t answer “where are you” by saying “with ____.” Think about your friend, spouse, parent asking “where are you” and you know they don’t know this person. It makes no sense to answer “with Eric.” Giving a location or saying “with this guy Eric I just met” or something is much more natural.
Two, if it’s not her sending the messages, why say she’s almost home? If whoever has her is sending these (or making her send them), this drastically reduces the amount of time before it’s suspicious that she’s not home. From past cases where someone has sent messages from a victim’s phone, I would expect something more like “I’m with this guy I just met, we’re going to hang out for a while, maybe go to another bar and be out pretty late..”
So many strange things with this one.
