I still think this was a random attack IMO. I don't really find it that odd simply because of other cases that have seemed like it HAD to be someone who knew the victim(s) and yet it was a stranger. Jayme Closs's abductor for instance--this huge tragedy happened because he happened to be stopped behind her bus one day and saw her getting on it. Then he shows up at her house, murders her parents, and abducts her. We all thought, this is personal, it HAS to be someone known to the victims, but...no. The same thing with Mollie Tibbets--she runs the same routes almost every day, such a small town, has to be someone she knows, but it was just a guy who happened to pass her running while he was driving down the road.
I wouldn't be surprised if BG was "trolling" the trails to find someone to either assault or kill. It is possible that was his intent that day, and tragically, the girls were there. Or it could be that he was walking the trails, had a weapon because he always carries a concealed weapon, and something about them "set him off" and it was unplanned on his part. I am torn on which I think it is. Neither makes this tragedy any better, of course. But IMO I don't think he knew they specifically were going to be there at that time. My understanding was the plans to go to the trails was rather last-minute by the girls (unless I have that fact wrong, which I might). So I don't know how many other people would even have the time to find out this info about their whereabouts.
