Hmm seeing that a previous renter of his AirBnB said he asked her a bunch of questions, seemed overly interested in her, tried to friend her, etc. I wonder if ML ever visited someone she knew who was staying at his AirBnB and that is how he got interested in her. I'm sure LE is looking into past renters of his place. She would have no reason to stay there, as she has her own place in SLC. But maybe a friend or acquaintance from out of town who was visiting SLC rented his AirBnB, she visited or came to pick them up or whatever, and he saw her, maybe talked to her for a bit, got her name, etc. They could have connected on social media after. This is all MOO, obviously, but it would explain a connection between them.
