Yet, he had pictures of her on his phone and they had matched on Tinder. Somehow, that match on Tinder (or perhaps in addition, another site), led to exchanging real phone numbers for texting. Then she texted back and forth with him. She would have seen his picture on Tinder. I find it really hard to believe she didn't know who she was meeting.
It's the why of the meeting that's curious. My own current guess is that he was doing webcam stuff at his house, perhaps posing as a producer of same. She may have been wanting a tidy webcam space to do some online convo with someone from one of her other web connections. She had been off line, so to speak, from that world for a few days while home in LA.
AA came across to people as a "nice guy" and he got many women to come to his house (according to previous roommates) probably by being affable or charming or both.
It's true he may have looked very different than his Tinder profile pics, though.
He could also have insisted that his own phone was off (for privacy) and hers had to be too, by grabbing it and turning it off. At that point, the car was already in motion and he changed the subject. I think a lot more will come out at trial and I do believe they will try him.
