Not sure if the site Crime Online is considered MSM, but they have an interview with the guy who last saw her jog by and here is the 10% of the article worth noting:
"(the witness) said the name-calling, such as being called “killer” and “pervert” by social media users online, while other people bang on his door, has stressed him out and scared his young daughter. He reiterated that the FBI already questioned him and he has not been named a suspect in Mollie’s disappearance."
Ok, now seriously, if anyone is wondering why a person who knew something would not come forward and tell the police, all one has to do is look at how they've treated some of the people who have so far. People need to be a little less "angry mob" and a little more "helpful citizen". JMHO
