GRAND JUNCTION – An investigation is underway after a man shot himself in the stomach, apparently by accident, at a country music festival in western Colorado.

The Grand Junction Daily Sentinel reports the 30-year-old man, whose name has not been released, shot himself Friday evening at the Country Jam festival. His condition has not been released.

Megan Terlecky, a spokeswoman for the Mesa County Sheriff’s Office, says investigators are trying to figure out how the man was able to bring the gun into the festival. No weapons are allowed on the festival grounds, and this year’s security is ramped up from previous festivals, including searches of small bags and the prohibition of backpacks or other large bags.
