I know early on when we were going over the Snapchat messages, there was talk about whether her friends could see where she was on a map. Sorry, I don’t use Snapchat so not totally familiar. Her parents said they’ve considered that this may have been set up by one of her friends. Possibly they could see her location and let him know? Or she could have been followed from her brother’s apartment. If IY is already in the Chevron when she walks in, this seems less likely. I know it looks like him by the door, but don’t think this has ever been confirmed. All just MOO.
