HELENA, Mont. (AP) — A former Yellowstone National Park concession worker has been sentenced to 10 years in prison after he was convicted for possession of child pornography.

James Durant was arrested at Old Faithful last October after an investigation by Montana, Wyoming and National Park Service employees led authorities to the 57-year-old concession worker.

Yellowstone officials say hundreds of images of child pornography were found on Durant's computers.

He was tried and convicted, and U.S. District Judge Scott Skavdahl sentenced Durant on March 15.

The 10-year prison sentence will be followed by a lifetime of supervised release.

Durant used to work in Yellowstone's Old Faithful area and in Grand Canyon National Park.
