PIKE NATIONAL FOREST, Colo. —  A-60-year old man was shot and killed while camping with his family Friday night in a secluded campground near Woodland Park.

The Douglas County Sheriff’s Office believes the man, who was identified Monday as Glenn Martin, was struck by a stray bullet fired about 6:30 p.m.

“It is not believed to be an intentional act at this time. However, that has not been ruled out,” the sheriff’s office said.

The search is continuing for the person who might have killed the camper and didn’t even know they did it.

Signs near the entrance of the Rainbow Falls Campground warn visitors that shooting is illegal, but gunshots could be heard Sunday and shotgun casing were found on several trails near the campsite where the man was killed in southwest Douglas County.

The sheriff’s office is asking for the public to help identify anyone who was in the area shooting a high-powered rifle.

Anyone with information is asked to call the major tip line at 303-660-7579.

The name of the man killed has not been released.
