I am convinced she was taken during her run.
It all comes back to the Fitbit...
- When Tibbetts' Fitbit pinged at a hog farm about 10 miles southeast of the house in Brooklyn, IA, where she was last seen, police searched the area but found nothing, Mortved(Mitch Mortvedt, spokesperson for the Iowa Division of Criminal Investigation) said. Source:

So they got a Fitbit "ping" at the hog farm. In order for the Fitbit to "ping", it was using GPS via her phone. In normal mode, Fitbits do not use GPS. The only way for it to get and use GPS information is for it to be put into an activity mode (running, biking swimming, etc). Mollie's Fitbit's (Alta HR) only activity mode is called MobileRun, which is activated through the Fitbit app on her phone. MobileRun is how one tracks their run, by providing heart rate, distance, and time overlayed on the GPS route data. When one finishes their run, they stop MobileRun(through the Fitbit app on the phone), which then shows the results and allows one to compare previous runs. So Mollie's Fitbit was using MobileRun when it "pinged" at or near the hog farm.
Putting all this together... Mollie activated MobileRun at the beginning of her run
but never stopped MobileRun. Combine this with her missing workout outfit, missing headphones, dogs in the basement, and an undisturbed house. I think it is almost certain Mollie was taken on her run. It also explains how LE is confident in their timeline.
