I find it interesting that they brought in the lady that works on missing persons cases in for statistics. Her message was that abductions are highly unlikely and not the norm for Iowa. In my opinion, someone close to Mollie did something. They were basically saying "We're onto you..."
Also, they confirmed that she was last seen in her running gear which would disprove some of our theory about something happening in her work clothes (i.e. red shirt) on the walk to her mothers that morning or being in her pjs.
I think they may have a suspect or suspects and are onto them but may not have enough evidence yet. If an abduction is highly unlikely for Iowa in regards to statistics....then that leads me to believe they have something else in mind.
