Authorities say a woman spotted in eastern Iowa was not Mollie Tibbetts.

TV9 reached out to authorities after a Facebook post was circulating on social media about a potential sighting of Mollie Tibbetts in Marion, Iowa at a gas station.

Tom Daubs from the Marion Police Department says the report was investigated and found to be in error. Daubs said officers on the scene determined it wasn't Tibbetts.
