KG did report a stalker. In one Incident police investigated and interviewed.The guys were pretty obvious about it and had an explanation.Curious that a even a random person describes BK as "a bit awkward" after a very short chat they had with him and his father when the Elantra was serviced. I don't think he's any good at stalking or blending in with any type of crowd. Even restaurant personnel thought him a creep and these people usually have pretty high creep "tolerance" so to say. Ninja he is not. It seems he would stand out any place he'd go, so it's a bit weird he wasn't noticed/reported by any of the victims considering how he most likely followed them for some time before he attacked. All just MHO.
Just speculation here in my part, but I think BK had enough schooling along with the answers to his ‘survey’ that he knew how to not be as noticeable.
I’m hoping that if KG was taking pictures or video he might show up in the background.
Just speculation / opinion by me
