UPDATE: Camper suffers gunshot wound
A Minnesota woman suffered a leg injury form a stray bullet at River's Edge campground Friday.
Sheriff John Shilts said Tuesday his department's investigation may have determined where the stray round came from.
"A 16-year-old and a 17-year-old were about one-half mile away shooting .22-caliber rifles," Shilts said. "We will have to wait for the results of a ballistics test to know for sure, but the slug is consistent with the ammunition they were using."
