I'm getting up to speed on this case, so if this next has already been discussed, I apologize---
But February 13 was a Monday. I know the girls had the day off from school, but this guy couldn't have a regular 9-5 job if he's out lurking on hiking trails in the middle of the day. This wasn't lunch time, it was smack dab during normal working hours. If this guy is on that trail that day, he may have been on that trail for many days. And that trail goes all over Delphi. He could have picked it up at any number of locations. I'm sure LE has looked into this, but someone must have seen him on another day as well. As in, he probably frequented that park for some time before he happened on these girls.
Delphi is not far from the Illinois border. But it's deep enough into the state, that it wouldn't be a spot that you would just happen on if you were traveling through. This guy is probably somewhat local. But maybe transient.
I think it's interesting that he's out, perhaps stalking victims on a Monday. I wonder if there have been other crimes like this on hiking trails in regions close by, even Illinois. Hiking trail killer Gary Michael Hilton traveled around. And though his object was financial gain, these hiking trail stalkers often jump for local to local, seeking victims of opportunity. They look nondescript,
I don't think for a minute that Molly Bish's abductor is the same as Abigail and Libby's killer. But look how ordinary both suspects look. They could be almost anyone.
