A longtime employee of the Petrified Forest National Park has admitted to stealing approximately $313,000 in park admission fees in court documents filed in the U.S. District Court.

Sharon Baldwin, 47, became a Supervisory Visitor Use Assistant at the park in 2008, and in court documents stated she began embezzling in September of 2010.

Baldwin accepted a plea agreement and was sentenced on Monday to one year in prison followed by three years probation. She was also ordered to pay restitution to the park service.
