Personally even if they met through a SD/SB arrangement; it still doesn’t take into account that he’s a VERY sick predator. He would find a way to do what he did regardless of the Avenue. I had a married friend in HS who was taken in the middle of the day in a high traffic shopping center parking lot on a Saturday by a creep who developed an obsession with her. He displayed disturbing tendencies before and it progressed to that. They find a way to commit their sick crimes.
