This train of thought sort of formed while I was sleeping—- it’s like my brain just keeps churning the info no matter what I’m doing!
Mollie disappeared on a summer Wednesday evening. Just a regular old weekday evening. Who is out and about then? People coming home from work. I am looking at that huge paving/construction company right on the edge of town in Brooklyn. In the Midwest, summer is a mad rush to get road work/construction projects done before the snow returns. They do road work 24/7 around the clock where I live.
I had the thought a construction worker may be involved. He could have been on his way home from a job site, perhaps stopped by that office building for something, happened to see Mollie on the road, and just snatched her. She would be no match for a strong guy like that.
He might move around to wherever the current job site is, but be familiar with the town of Brooklyn because the company office building is there. A varying work schedule could hide being home early/late from a wife/family. Cuts/dirt/bruises the norm and not even noticed.
That said, my gut tells me this person worked his way up to this and has committed other crimes. Which could tie in these sexual assaults that were happening to women on rural Iowa roads exactly one year ago:
Women assaulted on rural roads in Linn and Black Hawk Counties, deputies say
I looked at the locations on a map, and these assaults form a triangle across this same area. Again, they could coincide with job sites or routes the perp took for work. I looked all over and couldn’t find anything about this guy ever being caught.
My hunch— this is a “cool & collected” type of guy, 35-45 years old.
