WINFIELD TOWNSHIP, Pa. (KDKA) — State Police are investigating a report of a person claiming to be Cherrie Mahan, the 8-year-old girl who went missing from a bus stop in Pennsylvania in 1985. 

Cherrie was last seen in Winfield Township, in Butler County, and there’s been no sign of her for 39 years. 

Now State Police are investigating after a woman posted on social media claiming she is Cherrie Mahan.

Last month, the woman posted her claim in a Facebook group.

The Mahan family doesn’t believe her, but State Police are working with an out of state agency to positively identify the woman making the claim.

State Police have not made contact with the woman, and the out of state agency is trying to find her. 

Mahan was last seen getting off her school bus on Cornplanter Road in Winfield Township on Feb. 22, 1985. Police say a bright blue 1976 Dodge van with a mural of a mountain and a skier may be involved in her disappearance.

State police say the amount of time that has gone by makes this case difficult to solve.

Three other women throughout the years have claimed to be Mahan.

There’s still a $5,000 cash reward for anyone with information that leads to an arrest, solving the case or finding Mahan.
